Waves

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium vibrate parallel to the direction of the wave motion.

Front

What is the lowest point on a wave called?

Back

Trough.

Front

Through which mediums can sound travel?

Back

Sound can travel through solid, liquid, and gas.

Front

What is the term for the highest point on a wave?

Back

Crest.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the formula for wave velocity?

Back

v = λf, where v is velocity, λ is wavelength, and f is frequency.

Front

If a wave has a frequency of 50 Hz and a wavelength of 0.2 m, what is its velocity?

Back

10 m/s.

Front

What is a mechanical wave?

Back

A wave that requires a medium to travel through.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, particles vibrate perpendicular to the direction of wave motion, while in a longitudinal wave, they vibrate parallel.
