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

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is frequency?

Back

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

Front

How are wavelength and frequency related?

Back

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

Front

What is amplitude?

Back

Amplitude is the height of the wave from the rest position to the crest or trough, indicating the energy of the wave.

Front

What is visible light?

Back

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

Front

What type of waves have the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What is the formula to calculate frequency from wavelength?

Back

The formula is v = c/λ, where v is frequency, c is the speed of light (approximately 3.00 x 10^8 m/s), and λ is the wavelength.

Front

What is the order of the electromagnetic spectrum from low energy to high energy?

Back

The order is: Radio, Micro, Infrared, Visible Light, Ultraviolet, X-ray, Gamma.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.
