What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and highest energy in the electromagnetic spectrum. They are highly penetrating and can be dangerous to living tissues.

Front

What happens to energy and wavelength as the frequency of electromagnetic waves increases?

Back

As the frequency of electromagnetic waves increases, the energy increases and the wavelength decreases.

Front

Which electromagnetic waves have the highest energy?

Back

Gamma rays have the highest energy among electromagnetic waves.

Front

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

Back

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

Front

What are the different types of electromagnetic waves in order of increasing wavelength?

Back

The order from shortest to longest wavelength is: gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves, and radio waves.

Front

What are x-rays?

Back

X-rays are a form of electromagnetic radiation with a shorter wavelength than visible light, used in medical imaging.

Front

How do electromagnetic waves interact with matter?

Back

Electromagnetic waves can be absorbed, reflected, or transmitted by matter, depending on the material's properties and the wave's frequency.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with the longest wavelength, used for communication such as radio and television signals.

Front

What is the significance of ultraviolet rays?

Back

Ultraviolet rays have higher energy than visible light and can cause skin damage and increase the risk of skin cancer.
