Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

The full range of frequencies of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

Front

What is frequency in the context of electromagnetic waves?

Back

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

Front

What is wavelength in the context of electromagnetic waves?

Back

Wavelength is the distance between successive crests of a wave, usually measured in meters.

Front

How are frequency and wavelength related?

Back

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

Front

What type of electromagnetic radiation is used for medical imaging?

Back

X-rays are used for medical imaging to diagnose health issues in bones and teeth.

Front

Which type of electromagnetic radiation has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

Which type of electromagnetic radiation is used in remote controls?

Back

Infrared radiation is commonly used in remote controls.

Front

What is visible light?

Back

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

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasting.

Front

What is ultraviolet radiation?

Back

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