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 are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through the vacuum of space and consist of oscillating electric and magnetic fields.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks of a wave, typically measured in meters.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What type of electromagnetic wave has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

What are ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves that are invisible to humans but can help the body produce vitamin D.

Front

What are gamma rays used for?

Back

Gamma rays are used in medical treatments, including cancer therapy, due to their high energy.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye.
