Light bounces when it is 

• reflected
• absorbed
• refracted

Light bends when it is 

• refracted
• reflected
• absorbed

This is an example of...

Which explains why the fork looks different under water?

• light can't pass through the glass
• the wavelength of light lengthens
• the amount of light increases when going through water
• light is refracted at an angle

Another name for light bending is ....

• Reflaction
• Absorbing
• Refraction
• mirror

What does reflection mean?

• is the process in which light is bent, when it travels from one medium to another. 
• is the process in which light strikes a surface and bounces back off that surface. 
• is the process in which the light creates a shadow
