Electromagnetic Spectrum

Front

What are the different regions of the electromagnetic spectrum?

Back

The regions of the electromagnetic spectrum include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What are the colors of visible light in order of increasing wavelength?

Back

The colors of visible light in order of increasing wavelength are violet, blue, green, yellow, orange, and red.

Front

What does 'C' refer to in a wave diagram?

Back

In a wave diagram, 'C' refers to amplitude.

Front

What does 'A' refer to in a wave diagram?

Back

In a wave diagram, 'A' refers to wavelength.

Front

Which region of the electromagnetic spectrum has the longest wavelength?

Back

The region of the electromagnetic spectrum with the longest wavelength is radio waves.

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 the relationship between wavelength and frequency?

Back

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

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 in wavelength.

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 nanometers to 1 millimeter.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, typically ranging from about 10 to 400 nanometers.
