7. A photon has an energy of 5.53 x 10^-17 Joules when the frequency is
8.34 X 10^16 Hz. What will happen to the energy of the photon if the
frequency is decreased to 2.79 X 10^8 Hz? Note: 8, 16, & 17 are exponents.
The energy will decrease.
The energy will increase.
The energy will remain the same.
