Electromagnetic Spectrum

Front

What happens to the energy of an electromagnetic wave as its frequency increases?

Back

The energy of an electromagnetic wave increases as its frequency increases.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are electric and magnetic fields (energy) that travel through empty space very quickly.

Front

What do waves transfer?

Back

Waves transfer energy.

Front

How does light behave?

Back

Light behaves like both a particle and a wave.

Front

What is the correct order of waves in the electromagnetic spectrum?

Back

Radio, Micro, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

Define wavelength in the context of electromagnetic waves.

Back

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

Front

What is frequency in relation to electromagnetic waves?

Back

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

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.

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 type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.
