A photon of light has a wavelength of about 600 nm (1nm = 1 x 10-9 m). What is the energy of this photon of light? Show all calculations leading to an answer.

Answer 1

find the frequency from the wavelength
lambda = c T = c/f
then energy = Lank constant * frequency

Answer 2

ok thank you so much, have a great day :)

Answer 3

Given: wavelength=600 nm; h=6.62×10^-34
Solution:
Since, Energy=hc/wavelength
(6.62×10^-34×3.0×10^8)/600×10^-9
=3.39×10^-19J
=3.39×10^-19/1.6×10^-19 eV
=2.11875 eV
