The si unit of length is the meter, which is defined as the length equal to 1,650,763.73 wavelengths of the light emitted by a particular energy transition in krypton atoms. calculate the frequency of the light to three significant figures.

Frequency of light

Explanation:

We have been given only.

Wavelength

And have to find the frequency   that is

And speed of the light .

And now we have to convert the wavelength in terms of .For this we know that,

In one meter there are wavelengths of radiation. So each wavelength is .

Plugging the values of wavelength and speed of light.

We have frequency, Hertz

Finally the frequency of light up to three significant figures =

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
