What is the energy of a photon of wavelength 500 nm? (h = 6.63 x 10^-34 J s, c = 3.00 x 10^8 m/s)
Answer and explanation
Correct answer: B. 3.98 x 10^-19 J
- Step 1: . Step 2. J. Answer: 3.98 x 10^-19 J. Why not the others: 1.33 x 10^-27 is , the photon's momentum; 3.3 x 10^-40 is ; 7.96 x 10^-19 doubles the correct value.
