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 and the lowest frequency/energy.

Front

Which type of electromagnetic wave has the shortest wavelength?

Back

Gamma Rays have the shortest wavelength and the highest frequency/energy.

Front

What portion of the electromagnetic spectrum is visible to the human eye?

Back

Only a small part of the electromagnetic spectrum is visible to the human eye.

Front

What is wavelength?

Back

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

Front

Which electromagnetic wave has the lowest energy?

Back

Microwaves have the lowest energy among the options provided.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasting.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves.
