2. Incident ray and angle of incidence ray id different
3. Distinguish virtual and real

# data[].attributes.body
To draw the ray diagram properly

# data[].attributes.body
1. when the angle of incidence is 0, the ray of light will pass through straight
2. when the light ray travels from an optically less dense to an optically more dense medium, the light ray slows down and bends towards the normal
3. when the light ray travels from an optically more dense to an optically less dense, the light ray speeds up and bends away from the normal

how to draw ray diagram

# data[].attributes.body
1. draw image virtually

# data[].attributes.body
1. I learnt that images must be virtual and thus, drawn with dotted lines
2. The virtual ray from the image to the eye must be a straight line.
3. I learnt the about laws of refraction.

# data[].attributes.body
1. light passes straight through only when mediums have similar optical density

2. we only see the image of the object during refraction

# data[].attributes.body
1) The image of an object should be virtual, have dotted lines.
2)When the angle of incidence is 0 degrees, there is no light ray.
3)read the question properly.

# data[].attributes.body

2. Images must always be drawn with dotted lines

# data[].attributes.body
1) read properly with my eyes

# data[].attributes.body
I will be more cautious when reading ray diagrams, especially when the image is not drawn to be virtual.

# data[].attributes.body
1. I learnt that the virtual image should be drawn in dotted lines.
2. I learnt that when the angle of incidence is zero degrees, there is no bending of light between two boundaries of different optical densities.
