Electromagnetic Waves

Front

What is the electromagnetic spectrum (EMS)?

Back

The electromagnetic spectrum (EMS) is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, ordered by increasing frequency and energy.

Front

List the order of electromagnetic waves from low to high energy.

Back

Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma.

Front

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

Back

High frequency in electromagnetic waves corresponds to high energy and short wavelength.

Front

What is the order of visible light colors from shortest wavelength to longest wavelength?

Back

Violet, Indigo, Blue, Green, Orange, Yellow, Red.

Front

Which type of electromagnetic wave has the longest wavelength?

Back

Infrared rays have the longest wavelength and therefore the lowest frequency/energy.

Front

Which of the following does NOT belong in the electromagnetic spectrum: X-ray, sound wave, ultraviolet rays, microwaves?

Back

Sound wave does NOT belong in the electromagnetic spectrum.

Front

Define wavelength in the context of electromagnetic waves.

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters, and is inversely related to frequency.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

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

Front

Explain the concept of frequency in electromagnetic waves.

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz), and is directly related to energy.

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, ranging from approximately 400 nm (violet) to 700 nm (red).
