S8P4a Electromagnetic Vs. Mechanical

Front

What is an electromagnetic wave?

Back

A wave that can travel through matter and empty space, such as light and radio waves.

Front

What is a mechanical wave?

Back

A wave that requires a medium (solid, liquid, or gas) to travel through, such as sound waves.

Front

Can electromagnetic waves travel through a vacuum?

Back

Yes, electromagnetic waves can travel through a vacuum, unlike mechanical waves.

Front

What is the amplitude of a wave?

Back

The distance between the middle line or resting point and the crest of the wave.

Front

List the types of electromagnetic waves in order from highest to lowest frequency.

Back

Gamma rays, X-rays, UV rays, visible light, infrared, microwaves, radio waves.

Front

What is the frequency of a wave?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

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

Front

What type of wave is sound?

Back

Sound is a mechanical wave that requires a medium to travel.

Front

What is an example of a wave that can travel through empty space?

Back

Light is an example of an electromagnetic wave that can travel through empty space.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particles of the medium move parallel to the direction of the wave, while in transverse waves, the particles move perpendicular to the direction of the wave.
