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 and lowest frequencies, used for communication.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelengths and highest frequencies, often produced by radioactive atoms.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, ranging from red (lowest frequency) to violet (highest frequency).

Front

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

Back

As the wavelength of electromagnetic waves increases, their frequency decreases, and vice versa.

Front

What type of electromagnetic waves do we feel as heat?

Back

We feel infrared waves as heat; they are emitted by warm objects.

Front

What is the frequency of visible light compared to other electromagnetic waves?

Back

Visible light has a moderate frequency compared to other electromagnetic waves, such as radio waves (low frequency) and gamma rays (high frequency).

Front

What color of light has the highest frequency in the visible spectrum?

Back

Violet light has the highest frequency in the visible spectrum.

Front

What color of light has the lowest frequency in the visible spectrum?

Back

Red light has the lowest frequency in the visible spectrum.

Front

What are ultraviolet waves?

Back

Ultraviolet waves are a type of electromagnetic radiation with shorter wavelengths than visible light, often associated with sunburn.
