EM Spectrum Practice

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes waves of all frequencies and wavelengths.

Front

What type of wave has the largest wavelength and lowest frequency on the electromagnetic spectrum?

Back

Radio waves.

Front

What color in visible light has the highest frequency?

Back

Purple.

Front

What is the wavelength range of ultraviolet electromagnetic waves?

Back

Approximately 10^-8 meters.

Front

What type of electromagnetic wave has a larger wavelength than infrared waves and higher frequency than radio waves?

Back

Microwaves.

Front

What type of electromagnetic wave has the highest frequency?

Back

Gamma rays.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

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

Front

What are the main regions of the electromagnetic spectrum in order of increasing frequency?

Back

Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.

Front

What is the frequency range of visible light?

Back

Approximately 4 x 10¹⁴ Hz to 7.5 x 10¹⁴ Hz.

Front

What is the significance of the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, allowing us to perceive light and color.
