The Frequency of Light Calculation

What is the frequency of light emitted by a helium-neon laser with a wavelength of 633 nm?

The frequency of the light beam is 4.74 x 10^14 s^(-1).

When determining the frequency of light emitted by a helium-neon laser with a wavelength of 633 nm, we can use the formula C = f x λ, where C is the speed of light, f is the frequency of the light beam, and λ is the wavelength.

Given that the speed of light is universally the same at 3 x 10^8 m/s and the wavelength is 633 nm (or 633 x 10^(-9) m), we can calculate the frequency as follows:

f = C / λ = 3 x 10^8 / 633 x 10^(-9) = 4.74 x 10^14 s^(-1)

Therefore, the frequency of the light emitted by a helium-neon laser with a wavelength of 633 nm is 4.74 x 10^14 s^(-1).
