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 gamma rays?

Back

Gamma rays are electromagnetic waves with the shortest wavelengths and the highest frequencies, often produced by radioactive atoms and in nuclear explosions.

Front

Which color of visible light has the highest energy?

Back

Violet light has the highest energy among visible light colors.

Front

What happens to wavelength as frequency increases?

Back

As frequency increases, the wavelength decreases.

Front

What is wavelength?

Back

Wavelength is the distance from the peak of one wave to the peak of the next wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What are radio waves?

Back

Radio waves are electromagnetic waves with long wavelengths and low frequencies, commonly used for communication.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, ranging from red to violet.

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to view the inside of the body.

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).
