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) a photon in beam b has twice the energy of a photon in beam a. b) a photon in beam b has the same energy as a photon in beam a. c) beam b carries twice as many photons per second as beam a. d) the frequency of the light in beam b is twice as great as the frequency of the light in beam a. e) none of the above statements are true.
