• compression

• radio

• light

• x-ray

A part of the wave where the molecules are spread apart is called-

• wavelength

• compression

• direction of travel

• rarefaction

Which of these does not emit light waves?

• 
• 
• 
• 

One way in which light waves are different from sound waves is that light waves-

• can move through empty space

• are caused by rapid vibrations

• travel more slowly

• can be reflected

When compression waves move through matter, the molecules move-

• backward and forward

• in a circular motion

• in random directions

• up and down
