Wavelength and Frequency

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

Define wavelength.

Back

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

Front

Define frequency.

Back

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

Front

What happens to energy as wavelength increases?

Back

As wavelength increases, energy decreases.

Front

What type of waves have the shortest wavelength and highest frequency in the electromagnetic spectrum?

Back

Gamma rays.

Front

What type of waves have a long wavelength and low frequency?

Back

Radio waves.

Front

How does the frequency of visible light compare to infrared light?

Back

Visible light has a higher frequency than infrared light.

Front

What is the frequency of a wave with a wavelength of 2 meters if the speed of the wave is 340 m/s?

Back

Frequency = Speed / Wavelength = 340 m/s / 2 m = 170 Hz.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

Which type of electromagnetic radiation is less dangerous than most types?

Back

Microwaves are less dangerous than most types of energy on the electromagnetic spectrum.
