the source of all wave motion is a

• wave pattern

• harmonic object

• vibrating object

• region of variable high and low pressure

Unlike a transverse wave, a longitudinal wave has no

• amplitude

• frequency

• wavelength

• speed

• all of the above

In a longitudinal wave. the compressions and rarefactions travel in

• the same direction

• opposite directions

• none of these are correct

Which of the following is not a transverse wave?

• sound

• light

• radio

• all of the above

NGSS.HS-PS4-5

The vibrations of a transverse wave move in a direction

• along the direction of wave travel

• at right angles to the directions of wave travel

The vibrations of a longitudinal wave move in a direction

• along the direction of wave travel

• at right angles to the direction of wave travel

a 60 vibration per second wave travels 30 k in 1 s. Its frequency is

• 30 htz and it travels at 60 m/s

• 60 htz and it travels at 30 m/s

• neither
