Question

Which describes a relationship when calculating the energy of a photon?

Answer 1

the one that describes a relationship when calculating the energy of a photon is :
the energy of a photon is directly proportional to frequency
Energy of a Photon is calculated by :
E = hv   ,
v is frequency
As v increases, E will also be increased

hope this helps

Answer 2

A. The energy of the photon is directly proportional to frequency.
