A certain shade of blue has a frequency of 7.14 * 1014 hz. what is the energy of exactly one photon of this light?

For this problem, let's use the Planck's equation which is written below:

E = hv

where

E is the energy

h is Planck's constant equal to 6.626*10⁻³⁴ J·s

v is frequency

Solving for E,

E = (6.626*10⁻³⁴ J·s) (7.14*10¹⁴ s⁻¹)

E = 4.73*10⁻¹⁹ J
