Final answer:

The energy of a microwave photon with a frequency of 1.12 × 10¹² Hz is found by using the formula E = hf, resulting in 7.4256 × 10⁻²² joules.

Step-by-step explanation:

The energy of a microwave photon can be calculated using the equation E = hf, where h is Planck's constant and f is the frequency of the photon. Given the frequency of the microwave photon as 1.12 × 10¹² Hz and Planck's constant as 6.63 × 10⁻³⁴ J·s, we can plug these values into the equation to find the energy.

E = hf = (6.63 × 10⁻³⁴ J·s)(1.12 × 10¹² Hz) = 7.4256 × 10⁻²² J

Therefore, the energy of a microwave photon with a frequency of 1.12 × 10¹² Hz is 7.4256 × 10⁻²² joules.
