Properties of Waves

How are sound and light waves similar?

• both transmit energy
• both require a medium
• neither require a medium
• both transmit matter

Which of these CANNOT travel in empty space?

• electromagnetic waves
• mechanical

High energy waves have a ____. 

• high frequency
• low frequency
• small amplitude
• big wavelength

If a sound wave has a big amplitude, it will be a ____ sound.

• soft

• loud

• high frequency

• low frequency

Sound travels fastest through

• solids
• liquids
• gases
• empty space

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

Waves that require a medium are called 

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

Why would a wave change direction?

• Because it went from a medium to empty space
• Because it went from one medium to another
• the amplitude
• the amplitude of the wave
