Reflection and Refraction

The Law of Reflection States...

• When light hits a surface, it bends.

• When light is stopped from moving in a straight line, it creates a shadow.

• When light hits a surface, the angle of incoming light is equal to the level of outgoing light.

• Only mirrors can reflect light.

What is refraction?

• A bending of light when light travels at an angle into a substance with optical density.

• A bending of light that occurs when light is very flexible.

• When light bounces off of objects.

• When you turn the lights on and off really fast.

Light from the sun hits an object, and the light bounces back onto the wall, creating a direct beam. What could this object be, and which type of reflection is occurring?

• Mirror, diffuse reflection

• Paper, specular reflection

• Paper, diffuse reflection

Why does refraction occur?

• Change in the speed of light

• Change in the flexibility of light

• Change in the type of ray

• Refraction never occurs

How is reflection and refraction seen in rainbow formation? (Check multiple answers).

• Light entering a water droplet is refracted.

• Light rays hitting one another refract.

• Light reflects off of water droplets.

• Light reflects off the ground.
