'c' is your choice.
Answer:
Explanation:
The energy of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency light
On the other hand, there is an inverse relationship between and the wavelength :
(2)
Where:
is the speed of light
is the wavelength
Substituting (2) in (1):
(3)
Finally:
This is the energy of a photon of blue light, in Joules.
