A monochromatic light source used in a diffraction experiment has a wavelength of 4.60 x 10-
7 m. (a) What is the frequency of this light? When you input large numbers such as those in
this problem, then input the numbers with parenthesis so as to obtain the correct answer. (b)
What is the energy of a photon of this light?

  • Physics -

    f = speed/wavelength = 3*10^8m/s / 4.6*10^-7m = 6.5*10^14/s

    E = h*f = 6.6*10^-34 Js * 6.5*10^14/s = 4.3*10^-19J
