Sample Problems

Question 1

What is the wavelength (in cm) of radiation having a frequency of 8.74109 Hz?

Answer 1

Question 2

What is the energy, in joules, of a photon of wavelength of 522 nm?

Answer 2

Question 3

How do you solve problems asking for the wavelength of a photon?

Answer 3

C = (lamda) x (v)

(c) / (lamda) = v

E = hv = hc / (lamda)

==> E = (hc) / (lamda)
