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

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically ranging from about 1 millimeter to 100 kilometers.

Front

What happens to frequency as wavelength decreases?

Back

As the wavelength decreases, the frequency increases. This is because frequency and wavelength are inversely related.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, with wavelengths ranging from approximately 400 to 700 nanometers.

Front

List the electromagnetic waves in order of increasing wavelength.

Back

The order from shortest to longest wavelength is: Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared rays, Microwaves, Radio waves.

Front

What are microwaves?

Back

Microwaves are electromagnetic waves with wavelengths ranging from 1 millimeter to 1 meter, commonly used in communication and cooking.

Front

What is infrared radiation?

Back

Infrared radiation is electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, typically ranging from 700 nanometers to 1 millimeter.

Front

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

Back

The energy of electromagnetic waves is inversely proportional to their wavelength; shorter wavelengths have higher energy.

Front

What is ultraviolet radiation?

Back

Ultraviolet (UV) radiation is electromagnetic radiation with wavelengths shorter than visible light, ranging from about 10 nanometers to 400 nanometers.

Front

What are X-rays?

Back

X-rays are a form of electromagnetic radiation with very short wavelengths (about 0.01 to 10 nanometers) and high energy, commonly used in medical imaging.
