Q1232
The energy of a photon varies directly with its
A.
Wave length
B.
Frequency
AnswerC.
Speed
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.
