https://padlet.com/tec430/aeyxt23g7as3 Using your Lens and Mirrors table come up with three questions increasing in level of difficulty with the answer. Tier 1 (Knowledge Based: Requires person to identify information) Example: “What is the biggest city in Japan?” Tier 2 (Comprehension: Asks persons to take several bits of information and put them into a single category) Example: “If I put these three blocks together, what shape do they form?” Tier 3 (Application: Take information they already know and apply it to a new situation) Example: “How would you use your knowledge of latitude and longitude to locate Greenland?” en-us 2017-03-28 21:42:11 UTC 2025-11-05 04:39:00 UTC hello@padlet.com https://padlet.com/tec430/aeyxt23g7as3/wish/163275632 Tier 1

What is the difference between a mirror and a lens? 

Tier 2:
Compare and contrast a converging mirror, converging lens, diverging mirror, and diverging lens. 

Tier 3:

Which lens/ mirrors has a primary focal point on the left?
Concave lens and convex mirror
Tier 2:
How do you tell whether a virtual image is formed or a real image is formed?
The image is upside down and the size changes if the image is virtual.
Tier 3:
How would you use your knowledge of focal points to determine if an image gets smaller, gets larger, or stays the same if the real object is on the primary focal point in a convex lens?
The image will remain the same size. You know this since the image gets larger if it is in front of the focal point, and smaller if it is behind the focal point, so an average of this on the focal point gives you the same size image.]]> 2017-03-28 22:14:38 UTC https://padlet.com/tec430/aeyxt23g7as3/wish/163275759 https://padlet.com/tec430/aeyxt23g7as3/wish/163275841 1) If an object is outside the focal point on a concave mirror, then the image will be be..?
Answer: real and inverted. 
2) The bending of light as it travels from one medium to the other is called.....
Answer: Refraction
3)  Which of the following describes a light ray  that passes above the focal point and then is reflected by the mirrors?

Answer: is reflected back through the focal point ]]> 2017-03-28 22:15:35 UTC https://padlet.com/tec430/aeyxt23g7as3/wish/163275841 https://padlet.com/tec430/aeyxt23g7as3/wish/163276000 Tier 1: What type is image is formed for a concave, flat, and convex mirror?
Concave mirror: Real and virtual image. 
Convex mirror: Virtual image. 
Flat mirror: Virtual image 
Tier 2: What happens when you change the position of object in relation to the focal length?
 You change the size of the real image.  
Tier 3: How does the image change when you move the object more than 2 focal lengths, between one and 2 focal lengths, and less than one focal length? 
More than 2 focal lengths: Smaller, inverted, and real 
Between one and 2 focal lengths: Larger, inverted, and real. 
Less than one focal length: Larger, upright, and virtual.

Is the following a reflection off a concave or convex mirror? Calculate the height of the virutal image if the object is 2 feet away and 7 inches tall. The image appears 4 feet away.
