Electromagnetic Waves and Their Properties

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 perpendicular to each other and to the direction of wave propagation.

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 type of electromagnetic wave has a higher frequency than visible light?

Back

Ultraviolet waves have a higher frequency than visible light.

Front

What type of electromagnetic wave has the largest wavelength?

Back

Radio waves have the largest wavelength in the electromagnetic spectrum.

Front

Which type of electromagnetic wave has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

Front

What part of the electromagnetic spectrum can be seen by the human eye?

Back

The visible spectrum is the part of the electromagnetic spectrum that can be seen by the human eye.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

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 amplitude in a wave?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position to the crest or trough.

Front

What is the relationship between frequency and wavelength?

Back

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