Waves

What kind of wave is pictured below?

• compressional wave
• transverse wave
• sound wave
• mechanical wave

What do we call the bottom of a transverse wave?

• crest
• trough
• wavelength
• amplitude

What do we call the top of the wave?

• crest
• trough
• amplitude
• frequency

What happens when you increase the amplitude of a sound?

• it makes the sound louder
• it makes the sound travel faster
• it increases the wavelength of the sound
• it increases the frequency of the sound

Waves that require a medium are called 

• mechanical waves
• transverse waves
• light waves
• gamma rays

What do we call the part of a compressional wave that is when the waves are squeezed together?

• compression
• rarefaction
• crest
• trough

What do we call the part of a compressional wave that is spread a part?

• compression
• rarefaction
• crest
• trough
