Waves and the Electromagnetic Spectrum Review

Front

What are waves?

Back

Waves are disturbances that transfer energy from one place to another without transferring matter.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What type of wave is a sound wave?

Back

Sound waves are longitudinal waves.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What are microwaves used for?

Back

Microwaves are used for communication (like cell phones), cooking food, and in radar technology.

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What are ultraviolet rays?

Back

Ultraviolet rays are a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.
