c & E calculations

Front

What is the formula to calculate the frequency of light?

Back

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

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

How do you convert wavelength to frequency?

Back

Use the formula: f = c / λ, where c is the speed of light and λ is the wavelength.

Front

What is the energy of a photon in terms of frequency?

Back

Energy (E) = h * f, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency.

Front

What is Planck's constant?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

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

Back

Frequency = 3.00 x 10^8 m/s / 500 x 10^-9 m = 6.00 x 10^14 Hz.

Front

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

Back

Energy = h * f = 6.626 x 10^-34 J·s * 5 x 10^14 Hz = 3.31 x 10^-19 J.

Front

How do you calculate the wavelength from frequency?

Back

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

Front

What is the frequency of ultraviolet light with a wavelength of 1.24 x 10^-7 m?

Back

Frequency = 2.42 x 10^15 Hz.
