What is the frequency of a photon with a wavelength of 1040 nm. report your answers to three significant digits. the frequency is = s-1

Explanation:

The relation between frequency and wavelength is shown below as:

c is the speed of light having value

Given, Wavelength = 1040 nm

Also, 1 m = nm

So,  

Wavelength = m

Thus, Frequency is:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
