Question

The energy of a photon that has a wavelength of 8.33 × 10^-6 m is ________ J.A) 2.20 × 10^-26 B) 3.60 × 10^13C) 2.39 × 10^-20 D) 2.7 × 10^9E) 4.5 × 10^-25

Answer 1

The energy of a photon can be found using the following equation:

What we're going to do is to replace the values of the constant and the value of the wavelength in the expression above. This is:

Therefore, the correct answer option is C. 2.39 × 10^-20 J.
