Wavelength and Frequency of Light

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs of a wave.

Front

What is frequency?

Back

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 one increases, the other decreases.

Front

What is the formula to calculate the speed of light?

Back

Speed of light (c) = Wavelength (λ) × Frequency (f).

Front

What is the unit of frequency?

Back

Hertz (Hz), which is equivalent to cycles per second.

Front

How do you calculate the wavelength of a wave if you know its frequency?

Back

Wavelength (λ) = Speed of light (c) / Frequency (f).

Front

What is the energy of a photon?

Back

Energy (E) = Planck's constant (h) × Frequency (f).

Front

What is Planck's constant?

Back

Planck's constant (h) is approximately 6.626 x 10^-34 J·s.

Front

What type of waves are light waves?

Back

Light waves are electromagnetic waves.

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 m/s.
