Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

Which electromagnetic waves have the highest energy?

Back

Gamma rays.

Front

What type of medium can a mechanical wave not travel through?

Back

A vacuum (empty space).

Front

What unit is frequency measured in?

Back

Hz.

Front

What phenomenon occurs when light bends as it passes through different mediums?

Back

Refraction.

Front

What is the relationship between frequency and wavelength in a wave?

Back

As frequency increases, wavelength decreases.

What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 m/s.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
