Two Sources Emit Beams of Light of Wavelength 550 Nm

Multiple Choice

Two sources emit beams of light of wavelength 550 nm.The light from source A has an intensity of 10 µW/m²,and the light from source B has an intensity of 20 µW/m².This is all we know about the two beams.Which of the following statements about these beams are correct? (There could be more than one correct choice. )

A) Beam B carries twice as many photons per second as beam A.
B) A photon in beam B has twice the energy of a photon in beam A.
C) The frequency of the light in beam B is twice as great as the frequency of the light in beam A.
D) A photon in beam B has the same energy as a photon in beam A.
E) None of the above statements are true.
