1. How do we know that light rays travel in straight lines?
2. How does moving the object closer to or further from light source change the shasows size?
3. The law reflection states:(choose 1)
a. The angle of incidence will be wavy
b. The angle of incidence is equal to the angle of reflection
c. The angle of incidence is opposite to the angle of reflection.
4. If an incidence ray has an angle of 25° from the normal, the angle of reflection will be:(choose 1)
a. 45° b: 22° c: 25°
5. What is light refraction?
6. Do different types of medium affect refraction? Why or why not?
7. What tool can we use to measure the angle of incidence or angle of reflection?
8. How does the light bouncing off the paint affect how you see it when its being mixed?
