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.

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).

Front

What is a wave?

Back

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

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic waves emitted by radioactive materials.

Front

How does increasing the amplitude of a wave affect its energy?

Back

Increasing the amplitude of a wave increases the wave's energy.

Front

What happens to the energy of waves as the wavelength gets shorter?

Back

The energy of waves increases as the wavelength gets shorter.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, related to the wave's energy.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with long wavelengths, used for communication.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light, often associated with heat.
