Using the following materials (or other items), create a model to show as accurately as you can, how light rays behave! You should create for both reflection and refraction! =) You can be creative!
1) Light source
2) Mirror or glass block
3) Strings
4) Ruler
5) A small toy/object
6) Tape
After creating the 3D model, draw ray diagrams to represent the behaviour of light rays. Feel free to post any questions you have and we'll get back to you =)

# data[].attributes.body
1) Please post your Grp number and name in the title as shown above.

2) Then post a picture of your 3D model with a short description to explain your model. Include 2D drawing of your ray diagrams. Let your creative juices flow!

reflection : the torch = light source. hence I can see the spoon in the mirror.

Reflection. (2D description )
- the torch is the light source. When the mirror is in front if the toy car, the light ray reflects. Hence u see an image of the of the toy car. There is 2 types of rays. Incidence ray and the reflection ray the . The lines can tell you the direction of the light ray, as you can see, the light ray traveled in a straight line. The law of reflection is that the angle of Incidnece = angle of reflection.

Refraction, The toy car is an example of a light ray. There is a synthetic grass patch which is optically denser than the air. As the right wheel of the toy car touches the boundary of the normal, the speed of light ray slows down, and bent. Once the car goes away from the boundary of the normal, ( grass patch ) the speed of the light ray travels faster. ( F.A.S.T)

Light rays shine into the eye in the direction from the image of the correction tape. The image formed by the the mirror has the same distance with the object from the mirror, and it’s the same sizes.The line from the mirror to image is a reference line and not the light ray. The image is virtual and dotted lines represents virtual. The direction of the reflected rays is towards the eyes. The lines from the mirror to the image is drawn with dotted lines as it is virtual and not real. The normal line is a reference line that is perpendicular to the mirror. While the angle of incidence is the same as the angle of reflection, it is called the law of reflection.

# data[].attributes.body
The incident ray hits the mirror and is reflected by the mirror in the direction of the image.

# data[].attributes.body
The Torchlight is the light source.When the mirror is in front of the object,the light ray reflects thus being able to see an image on the mirror.the arrows show the direction of the light ray and the lines refer to lights properly of which light travels in a straight line.

The glass block is optically denser than air thus when the object enters the glass block the speed of the light ray slows down causing the object to move towards the normal but when the object leaves the glass block the light rays travel faster causing the object to move away from the normal.

# data[].attributes.body
Refraction occurs when a light rays gets bend while travelling from one object to the another object due to change in the speed of light or change in the direction.

# data[].attributes.body
If the surface is smooth and shiny, like glass, the light will reflect at the same angle as it hit the surface.

# data[].attributes.body
Refraction.A toy car is a good representation of a light ray.The glass block is optically denser than air.The toy car’s right wheel will touch the optically denser surface first, which slows the car down and therefore the toy car travels away from the normal. When the toy car touches the less optically dense area , it will speed up, which is how light rays behave

# data[].attributes.body
This my model of light( sorry for blurry mirror ).

# data[].attributes.body
the light will first shine to the object and then get reflected to the eye. that’s a reflection

# data[].attributes.body
refraction occurs when light rays get bend sue to the change of speed in light or object

# data[].attributes.body
Reflection: The light rays from the torch get reflected off the mirror and into our eyes. The distance between the image and the mirror is the same as the distance between the object and the mirror.

The torch light is the light source. The light source wil be reflected by the mirror and bounce into The Eye.

Refraction occured because when the pencil was inside the cup of water, the image of the pencil is bent. It is because water is optically less dense than air, so when the pencil was inside the cup of water, the speed of light slowed down

My diagram for reflection, when the light ray hits the mirror, the image will be formed by the mirror and will have the same distance apart from the mirror as the object.

# data[].attributes.body
This is 3D diagram of reflection.

# data[].attributes.body
refraction occurs when the light rays enter something optically less or more dense and bends towards or away from the normal. As shown in the diagram, the light ray travels into the glass block which is optically less dense than air so it slows down and bends towards the normal.

# data[].attributes.body
Refraction occurs when light rays enter a different mediums like light rays entering water which is optically denser than air.

# data[].attributes.body
Reflection:
The torchlight act as a light source and the light ray hits the mirror. The real image of the ball and the reflected image of it is the same size. The dotted lines means virtual and represent the distance between the both image. The reflected rays is going towards the eye thus being able to see the image of the ball.

# data[].attributes.body
The object will be reflected off the mirror and the person can see the object

My 3D model. Diagram is in a separate response

The empty cup on the left has the same optical density throughout as it contains air. Hence no refraction of light occurs. However, when there is two different mediums, one of which is the normal,has different optical density. Air, which is optically less dense, while water(the normal ) is optically more dense. When the light touches the boundary, it goes towards the normal F.A.S.T ( S.T = Slower Towards) and hence the speed of the light ray slows down, causing refraction. This is why the straw appears to look bent.

# data[].attributes.body
The light is reflected by the mirror and into our eye.this way,we are able to see the object.the incident rays is going towards the mirrors and the reflected rays enter our eyes

# data[].attributes.body
When light enters the water,it is bent.the image we see in the water is virtual.it is not real.as light bends in water,the image is above the actual object and we seethe image.this is why the pencil appears bent.this is caused when light is refracted.

# data[].attributes.body
Refraction is when light enters a different medium, which in this case is water. Water is optically denser than air, so the light turns toward the normal and appears bent.

# data[].attributes.body
When the light shines onto the object, the light ray will shine into the mirror and the reflected ray will reflect into our eyes.

Reflection occurs when the light ray hits the mirror, the image will be formed in the mirror and will have the same appearance and distance apart from the object before the mirror.

# data[].attributes.body
When the light ray enters the glass block, the speed of the light ray decreases as the glass block is optically more dense than air, causing the object to move towards the normal. When the ray leaves the glass block, it moves away from the normal

# data[].attributes.body
this is my refraction picture. the water is optically more dense compared to air which is optically more dense , hence the pencil appears bent. when the light touches the boundary( surface of water) ,it goes towards the normal and the speed of the light ray slows down, hence this causes refraction.

# data[].attributes.body
Refraction occurs when light enters a different medium which in my diagram is water. Since water is optically denser than air, the light rays turn toward the normal and appears bent.

This is my 2D refraction diagram. The pencil appears to be bent because water is optically more dense than air, when light travels to different mediums, the speed of light would change , hence causing refraction.
