A. decreases
C. increases
B. remains the same
D. become doubled​


Sagot :

Answer:

C. Increases

Explanation:

All photons travel at the speed of light. ... From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.
