Two Sources Emit Beams of Light of Wavelength $550 \mathrm {~nm}$

question 61

Multiple Choice

Two sources emit beams of light of wavelength $550 \mathrm {~nm}$ . The light from source A has an intensity of $10 \mu \mathrm { W } / \mathrm { m } ^ { 2 }$ , and the light from source $B$ has an intensity of $20 \mu \mathrm { W } / \mathrm { m } ^ { 2 }$ . 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 the same energy as a photon in 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) Beam B carries twice as many photons per second as beam A.
• E) None of the above statements are true.
