Electromagnetic Waves (wave properties)

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that consists of oscillating electric and magnetic fields, which propagate through space at the speed of light.

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

Which color of visible light has the highest energy?

Back

Blue light has the highest energy among visible colors.

Front

What is a photon?

Back

A photon is a particle of light that carries energy and momentum.

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 300,000 km/s).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What type of wave has the longest wavelength in the electromagnetic spectrum?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What type of wave has the shortest wavelength in the electromagnetic spectrum?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

How does the frequency of a wave relate to its energy?

Back

The energy of a wave is directly proportional to its frequency; higher frequency waves carry more energy.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, ranging from red (longest wavelength) to violet (shortest wavelength).
