The wavelength of some yellow light is 580.0 nm. what is the frequency of this yellow light?

The frequency of yellow light of wavelength 580 nm is  

Further Explanation:

Wavelength is the characteristic property of a wave. The term wavelength is defined as the distance between two successive crests or troughs in a wave. It is represented by and its SI unit is meter (m).

The term frequency is defined as the number of times n event occurs in unit time. It is generally applied to waves including light, sound and radio waves. It is denoted by and its SI unit is Hertz (Hz).

The conversion factor to convert nm to m is,

The wavelength and frequency of light are related to each other by the following expression,

                                  ......(1)

Here,

C is the speed of light.

is the frequency of light.

is the wavelength of light.

Rearrange equation (1) to calculate the frequency of light.

                     ......(2)

The wavelength of yellow light is 580 nm.

Firstly, wavelength of yellow light is to be converted from nm to m as follows:

The speed of yellow light is .

The wavelength of yellow light is  .

Substitute these values in equation (2)

So the frequency of yellow light is .
