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 is the relationship between wavelength and frequency?

Back

As the wavelength decreases, the frequency increases. This means that shorter wavelengths correspond to higher frequencies.

Front

Which type of electromagnetic waves has the highest energy?

Back

Gamma rays have the highest energy and are the most dangerous type of electromagnetic waves.

Front

What are the characteristics of gamma rays?

Back

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

Front

Which color of visible light has the shortest wavelength?

Back

Violet light has the shortest wavelength among the colors of visible light.

Front

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

Back

The energy of electromagnetic waves increases as their frequency increases.

Front

What type of electromagnetic waves are used in communication?

Back

Radio waves are commonly used in communication technologies such as radio and television broadcasting.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (km/s).

Front

What are x-rays used for?

Back

X-rays are used in medical imaging to view the inside of the body, particularly bones and teeth.

Front

What is infrared radiation?

Back

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