Wavelength, Frequency

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 fixed point in a given amount of time, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 3.0 x 10^8 m/s.

Front

How do you calculate wavelength from frequency?

Back

Wavelength (λ) can be calculated using the formula: λ = speed of light (c) / frequency (f).

Front

What color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible spectrum.

Front

What color of light has the longest wavelength?

Back

Red light has the longest wavelength in the visible spectrum.

Front

What is the energy of a photon related to?

Back

The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.

Front

What is the formula for wave speed?

Back

Wave speed (v) can be calculated using the formula: v = frequency (f) x wavelength (λ).

Front

What happens to energy as wavelength decreases?

Back

As wavelength decreases, the energy of the wave increases.
