• Infrared rays

Which of the following electromagnetic waves is given off as heat? 

• Radio Waves
• Infrared Rays
• Visible Light
• Gamma Rays

Define refraction

• the bouncing back of light
• the echo of light
• the bending of light waves
• the spectrum of light

Which of the following happens when light bounces off a surface?

• reflection
• refraction
• electromagnetic
• spectrum

The _______________ determines the color of visible light.

Two children on a playground are playing outside in the sun.  One child is wearing a black shirt and the other is wearing a white shirt.  Why is the black shirt warmer than the white shirt? 

• The child wearing the black shirt is warmer than the child wearing the white shirt 
• The child wearing the white shirt is warmer than the child wearing the  black shirt
• The white shirt absorbs more visible electromagnetic waves than the black, which reflects all visible electromagnetic waves 
• The black shirt absorbs more visible electromagnetic waves than the white, which reflects all visible electromagnetic waves. 

Which of the following happens when light hits a new medium and bends as it passes through it?

• reflection
• refraction
• electromagnetic
• spectrum
