Multiple Choice

Ampitude is

• how fast a wave travels

• the direction a wave travels

• how much energy is carried in a wave

• the substance a wave goes through

Multiple Choice

ampltude in a transverse wave is

• how far apart waves are

• the baseline of a wave

• how far away from base line a wave is

Multiple Choice

which is true about amplitude in a longitudinal wave?

• how high from baseline a wave goes

• closer together means more energy

• bands farther apart means more energy

Multiple Choice

what is wavelength?

• distance between same parts different waves

• the substance a wave travels through

• how fast a wave travels

• how much energy a wave carries

Multiple Choice

Which is true about a transverse wave?

• compressions are closer together

• rarefractions are closer together

• crests are the highest parts and troughs are the lowest

• troughs are the highest parts and crests are the lowest

Multiple Choice

Which is true about longitudinal waves?

• Compressions are close together

• Rarefractions are close together

• crests are the highest parts and troughs are the lowest

• troughs are the highest parts and crests are the lowest

Multiple Choice

what is frequency?

• how much energy a wave carries

• how fast a wave travels

• distance between crests of a wave

• material a wave travels through

Multiple Choice

waves that are closer together

• have greater amplitude

• have greater wavelength

• have greater frequency

• have greater rarefractions
