Post Module Assessment #25

[Esther Ahn 4I]

Photoelectric experiments gave rise to a new equation relating the energy of light to its frequency. Select the right equation.

A. λv = c
B. Ek = mv2/2
C. mv2/2 = hv - φ
D. E = hv
E. None of the above

I put C as my answer, but this was incorrect. Can someone tell me the correct answer and why that is the correct answer?

[Hanlin Zhu 4G]

I think it might be D, because E=hv=hc/λ is connecting v, the frequency, with the energy of the photon.

[Tamera Scott 1G]

I agree, E=hv has both energy, (E) and frequency (v) in the equation, so it solidifies their relationship.
