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 given point in one second, measured in Hertz (Hz).

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 the speed of light in a vacuum?

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 = c/f, where c is the speed of light and f is the frequency.

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 its wavelength?

Back

The energy of a photon is inversely proportional to its wavelength; shorter wavelengths have higher energy.

Front

What is the frequency of blue light?

Back

Blue light has a frequency range of approximately 6.0 x 10^14 Hz to 6.5 x 10^14 Hz.

Front

What happens to the wavelength as the frequency increases?

Back

As frequency increases, the wavelength decreases.
