What is the frequency of a photon with a wavelength of 159 nm. Report your answers to three significant digits. The frequency is = s-1

Answer

Explanation:

Frequency reffers to the number of occurrences of a repeating event per unit of time. It is measured in units of hertz (Hz), it can also be measured as occurrence of a repeating event per second as well

c is the speed of light having value 3*10^8m/s

Given, Wavelength = 159 nm

But n= 10^-9m

Wavelength=159*10^-9

C=frequency* wavelength

Frequency=c/wavelength

Frequency= 3*10^8/159*10^-9

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
