Electromagnetic waves

Front

What is the full range of frequencies of electromagnetic radiation called?

Back

The electromagnetic spectrum.

Front

What happens to the energy of an electromagnetic wave as its frequency increases?

Back

The energy increases.

Front

Which type of electromagnetic wave has the longest wavelength and the lowest frequency/energy?

Back

Infrared rays.

Front

What is the range of the visible light spectrum?

Back

Between infrared rays and ultraviolet rays.

Front

What does high frequency in electromagnetic waves correspond to?

Back

High energy and short wavelength.

Front

Define electromagnetic waves.

Back

Electromagnetic waves are waves of energy that travel through space at the speed of light, consisting of oscillating electric and magnetic fields.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Approximately 299,792 kilometers per second (or about 300,000 kilometers per second).

Front

List the types of electromagnetic waves in order of increasing frequency.

Back

Radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, gamma rays.

Front

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

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be detected by the human eye, typically ranging from about 400 to 700 nanometers.
