Two lasers, A and B emit light of the same wavelength. If the intensity of A is greater than that of B, which of the following statements would be the correct interpretations of this situation using the wave and particle models of light.
A. Wave model is The amplitude of LASER A is greater than that of LASER B. ; Particle model isLASER A emits more photons per second than LASER B.
B. Wave model is he amplitude of LASER B is greater than that of LASER A. ; Particle model is LASER B emits more photons per second than LASER A.
C. Wave model is The amplitude of LASER A is greater than that of LASER B. ; Particle model is LASER B emits more photons per second than LASER A.
D. Wave model is he amplitude of LASER B is greater than that of LASER A. ; Particle model is LASER A emits more photons per second than LASER B.
参考答案: A

Explanation: The wave model assumes that the energy from the light is delivered in one continuous wave. As the wavelengths of the lasers are equal, the property that would increase intensity would be the amplitude of the light wave. In the particle model, light is composed of photons. The photon energy for each laser is equal, so a higher intensity is achieved by when there are more photons emitted per second.
