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

Which type of electromagnetic wave has the longest wavelength?

Back

Microwaves have the longest wavelength in the electromagnetic spectrum.

Front

What is the order of the electromagnetic spectrum from longest to shortest wavelength?

Back

The order is: Radio Waves, Microwaves, Infrared, Visible Light, Ultraviolet, X-rays, Gamma Rays.

Front

What are radio waves?

Back

Radio waves are the type of electromagnetic radiation with the longest wavelength and lowest frequency.

Front

How does wavelength relate to energy in electromagnetic waves?

Back

Shorter wavelengths have higher energy, while longer wavelengths have lower energy.

Front

Which electromagnetic wave has the shortest wavelength and highest frequency?

Back

Gamma rays have the shortest wavelength and the highest frequency in the electromagnetic spectrum.

Front

What is the frequency of a wave?

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 visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, ranging from red to violet.

Front

What are microwaves used for?

Back

Microwaves are used in various applications, including cooking food, communication, and radar technology.

Front

What is infrared radiation?

Back

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