Question

find the energy of each of photons which.........1. light of frequency=3x10to the power 15 hz....... 2. have wave length of 0.50A0 E=???​

Answer 1

E = hv

substitution of values, E = 19.86 × 10-¹⁹

E = hc/ wavelength

substitution of values, E = 39.75 × 10-¹⁶

(0.50 A⁰ = 0.50 × 10-¹⁰ m)

(h = 6.626× 10-³⁴ Js)

hope it helps
