Component P, because being supported by ample evidence is a characteristic of a hypothesis.
Answer:
is the energy of one photon of this radiation.
Explanation:
where,
E = energy of photon
h = Planck's constant =
c = speed of light =
= Frequency of the radiation
= wavelength of the radiation":
We have :
Energy of the photon of the radiation :
is the energy of one photon of this radiation.
