Energy Frequency

Question

A photon has a frequency of 8.01 × 10⁸ Hz. What is the energy of this photon in Joules? (h = 6.626 × 10⁻³⁴ J • s)

Answer 1

Frequency (v) = 8.01 × 10⁸ Hz = 8.01 × 10⁸ s^-1

Plank's Constant (h) = 6.626 x 10^-34 Js 

Energy (E) = ? Joules

Equation:

Energy (E) = Planks Constant(h)Frequency(v)

E = hv

E = (8.01x10⁸ s^-1) (6.626 × 10⁻³⁴ J.s)

E = 5.3 x 10^-25J
