A chemist has two lasers, Laser-A and Laser-B. It is observed that the two lasers emit visible light and that the wavelength of the light emitted by Laser-A is half as long as the wavelength of the light emitted
by Laser B. Which of the following statements could possibly be true?
(a) Laser-B will have photons that are twice as energetic as those of Laser-A.
(b) The frequency of the photons emitted by Laser-B will be twice that of the photons emitted by LaserA.
(c) Laser-A emits red light and Laser-B emits yellow light.
(d) All of these statements could possibly be true.
(e) none of these statements could possibly be true
