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

Which type of electromagnetic wave has the longest wavelength?

Back

Radio Waves have the longest wavelength in the electromagnetic spectrum.

Front

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

Back

As the frequency of an electromagnetic wave increases, the amount of energy in that wave increases.

Front

What is wavelength?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

High frequency waves have short wavelengths, while low frequency waves have long wavelengths.

List the types of electromagnetic waves in order from longest to shortest wavelength.

Back

Radio, Micro, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

What is the frequency of a wave?

Back

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

Front

What is amplitude in the context of waves?

Back

Amplitude is the height of the wave from its rest position, indicating the energy of the wave.

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are the type of electromagnetic radiation used in microwave ovens.

Front

What is visible light?

Back

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