PC Intro to Waves

Front

What is the highest point on a wave called?

Back

The crest.

Front

What is the lowest point on a wave called?

Back

The trough.

Front

Why can't sounds be heard in outer space?

Back

Because there is no medium.

Front

What does the amplitude of a wave represent?

Back

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

Front

What do all waves carry as they travel?

Back

Energy.

Front

What is wavelength in the context of waves?

Back

The distance between two consecutive crests or troughs.

Front

What is the relationship between frequency and wavelength?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is a medium in the context of wave propagation?

Back

The substance through which a wave travels.

Front

What type of wave requires a medium to travel?

Back

Mechanical waves.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel.
