Front

What happens to the wavelength as you move from radio waves to gamma rays in the electromagnetic spectrum?

Back

Wavelength decreases.

Front

What is the frequency of a wave that completes 3 cycles in one second?

Back

3 Hz.

Front

What type of recording device is most reliable for storing a song?

Front

What can be concluded about sound and vibrations in a vacuum?

Front

Which medium is most likely a vacuum if sound is measured at 30 meters away from an airhorn?

Back

Medium I.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through the vacuum of space and consists of oscillating electric and magnetic fields.

Front
