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

Which type of electromagnetic wave has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

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

Back

As the wavelength decreases, the frequency increases, and vice versa.

Front

What is the unit of measurement for frequency?

Back

The unit of measurement for frequency is Hertz (Hz).

Front

Which electromagnetic wave has the highest frequency?

Back

Gamma rays have the highest frequency in the electromagnetic spectrum.

Front

Which electromagnetic wave has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

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 kilometers per second).

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, typically ranging from wavelengths of about 400 nm (violet) to 700 nm (red).

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, typically ranging from about 700 nm to 1 mm.
