Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic waves emitted by radioactive materials. They have the shortest wavelength and highest frequency in the electromagnetic spectrum.

Front

How does wavelength relate to energy in electromagnetic waves?

Back

As the wavelength of electromagnetic waves gets shorter, the energy of the waves increases.

Front

What is a wave?

Back

A wave is a repeating pattern that can transfer energy through space or a medium.

Front

What is amplitude in relation to waves?

Back

Amplitude is the height of a wave from its resting point, indicating the energy of the wave.

Front

What are microwaves?

Back

Microwaves are a type of electromagnetic radiation with longer wavelengths than infrared light. They are used in cooking and communication.

Front

What is frequency in the context of waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What are radio waves?

Back

Radio waves are the longest wavelength electromagnetic waves, used for communication such as radio and television signals.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with shorter wavelengths than visible light, known for its ability to cause sunburn.
