Question

The wavelength of some green light is 530.0 nm. what is the frequency of this green light?

Answer 1

The answer to this question is 5.66 x (10^14) Hz

Explanation: Recall that the frequency of a light wave is the speed of light divided by the wavelength in meters.

You are given the wavelength of the light in nanometers, but the denominator of the formula is in meters. In this case, multiply 530.0 nm by 10^-9 m, resulting 5.3 * (10^-7) m.

After the conversion, divide the speed of light which is 3.0 x (10^8) m/s by the wavelength in meters. The final answer should be 5.66 x (10^14) Hz.

**Depending on the usage of significant figures, you may have to round to the nearest specified decimal value or truncate it at the nearest specified place value.**

Answer 2

Frequency is calculated by dividing the speed of light by the wavelength. Using the normal constant of 3x10^8 m/s divided by 530 nm you can calculate it. You need to convert nm to m so it is 5.3x10^-7. Divide the constant of light by that and you get 5.66 x10^14 hz, where hz is the function 1/s.
