Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

Which electromagnetic waves are given off as heat?

Back

Infrared Rays are the electromagnetic waves that are primarily felt as heat.

Front

What color in the visible light spectrum has the highest frequency?

Back

Violet has the highest frequency among the colors in the visible light spectrum.

Front

What is frequency in terms of waves?

Back

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

Front

What is the distance between two crests or two troughs of a wave called?

Back

The distance between two crests or two troughs of a wave is called wavelength.

Front

What are microwaves used for in law enforcement?

Back

Microwaves are used by police to test the speed of vehicles with RADAR technology.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What type of electromagnetic radiation can cause sunburn?

Back

Ultraviolet (UV) rays can cause sunburn and skin damage.

Front

What is the speed of light in a vacuum?

Back

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

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to its crest or trough, indicating the energy of the wave.
