Light Waves Review

Which waves have some electrical and some magnetic properties?

• Longitudinal

• transverse

• mechanical

• electromagnetic

Electromagnetic waves can transfer energy without a(n)

• change in either electric or magnetic field

• medium

• magnetic field

• electric field

Light is produced by

• vibrating electric and magnetic fields
• vibrations of electric fields
• vibrations of magnetic fields
• vibrations of particles colliding

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

The number of wavelengths that pass a point each second

• crest
• amplitude
• frequency
• pitch

The number of wavelengths that pass a point each second

• crest
• amplitude
• frequency
• pitch

The shorter the wavelength the 

• shorter the frequency
• higher the freuqnecy
• frequency stays the same
• less energy

Sound is produced by

• music
• vibrations of molecules
• Electromagnetic Waves 
• Transverse Waves 

How does a sound wave interact with a human ear?

• vibrates the ear drum
• bounces off the ear canal
• rotates the ear drum
• vibrates the ear canal

A medium can be a .....

• solid
• liquid
• gas
• all of the above
