The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1
Using the formula;
E =hf
Where
E = Energy of the photon
f = Frequency of photon
h = Plank's constant = 6.6 * 10^-34 Js
To obtain the energy in Joules;
E = 3.02 × 10^11 J/mol/6.02 * 10^23 mol
= 5 * 10^-13 J
f = E/h
f = 5 * 10^-13 J/6.6 * 10^-34 Js
f = 7.5 * 10^20 s−1
f = c/λ
c = speed of light = 3 * 10^8 m/s
λ = c/f
λ = 3 * 10^8 m/s/7.5 * 10^20 s−1
λ = 4.0 * 10^-13 m
The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1
