Electromagnetic / Mechanical Waves

Front

What is a medium in the context of sound waves?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel.

Front

What portion of the electromagnetic spectrum is made up of visible light?

Back

Only a small portion.

Front

Which type of wave is a radio wave?

Back

A radio wave is an electromagnetic wave.

Front

What type of wave is characterized by particle displacement parallel to the direction of wave propagation?

Back

Longitudinal wave.

Front

What does the blue section of a wave represent?

Back

Wavelength.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have particle displacement perpendicular to wave direction, while longitudinal waves have particle displacement parallel to wave direction.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum; it requires a medium.

Front

What is the amplitude of a wave?

Back

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

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).
