5B:Electromagnetic Spectrum Review (2024)

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, X-rays, and gamma rays.

Front

What type of wave is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What type of wave is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave's travel.

Front

What are X-rays used for in medicine?

Back

X-rays are used to create images of the inside of the body, helping doctors detect broken bones and other medical conditions.

Front

What happens to the energy of a wave when its amplitude increases?

Back

The energy of the wave increases when its amplitude increases.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the highest energy and shortest wavelength, often used in cancer treatment.

Front

What are infrared rays?

Back

Infrared rays are electromagnetic waves with longer wavelengths than visible light, commonly associated with heat.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).

Front

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

Back

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

Front

What are ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves with shorter wavelengths than visible light, known for their ability to cause sunburn.
