EM Spectrum practice

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 color of visible light has the longest wavelength?

Back

Red has the longest wavelength in the visible light spectrum.

Front

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength in the visible light spectrum.

Front

What is the relationship between wavelength and energy in the electromagnetic spectrum?

Back

As the wavelength decreases, the energy increases. Shorter wavelengths correspond to higher energy.

Front

What type of electromagnetic radiation has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are used in microwave ovens to heat food.

Front

What is the frequency range of radio waves?

Back

Radio waves have frequencies ranging from about 3 kHz to 300 GHz.

Front

What is infrared radiation commonly used for?

Back

Infrared radiation is commonly used in remote controls, thermal imaging, and heating.

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, ranging from approximately 400 nm (violet) to 750 nm (red).

Front

What is ultraviolet (UV) radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, typically ranging from 10 nm to 400 nm.
