Energy, Wavelength and Frequency

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.

Front

What is the formula to calculate the wavelength of a wave?

Back

Wavelength (λ) = Speed of Light (c) / Frequency (f)

Front

What is the unit of measure for wavelength?

Back

The unit of measure for wavelength is meters (m).

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the unit of measure for energy?

Back

The unit of measure for energy is Joules (J).

Front

What is the unit of measure for frequency?

Back

The unit of measure for frequency is Hertz (Hz).

Front

How does energy relate to frequency and wavelength?

Back

Energy is directly proportional to frequency and inversely proportional to wavelength.

Front

What is the energy of a photon with a frequency of 5 x 10^14 Hz?

Back

Energy (E) = h * f, where h = Planck's constant (6.626 x 10^-34 J·s). E = 3.313 x 10^-19 J.

Front

What is Planck's constant?

Back

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

Front

What is the frequency of a wave with a wavelength of 500 nm?

Back

Frequency (f) = Speed of Light (c) / Wavelength (λ). f = 6.00 x 10^14 Hz.
