Calculate the energy (in Joules) of a single photon of blue light with a frequency of 6.10 × 10¹⁴ Hz. (h = 6.626 × 10⁻³⁴ J • s)

Answer 1

Use E = hν

E = energy = ?

h = Plank's constant = 6.626x10^-34 Js

ν = frequency in Hz (s^-1)

Solve for E...

E = (6.626x10^-34 Js)(6.10x10¹⁰ s^-1)

E = 4.04x10^-23 J
