    Answer:

    Number of photons emit per second = 1.9 × 10²⁹  (Approx)

    Explanation:

    Given:

    Frequency = 91.5 MHz

    Power = 11.5 Kw = 11,500 J/s

    Find:

    Number of photons emit per second

    Computation:

    Total energy with frequency (E) = hf

    Total energy with frequency (E) = 6.626×10⁻³⁴  × 91.5×10⁶

    Total energy with frequency (E) = 6.06×10⁻²⁶ J

    Number of photons emit per second = 11,500 / 6.06×10⁻²⁶

    Number of photons emit per second = 1897.689 × 10²⁶


    Number of photons emit per second = 1.9 × 10²⁹  (Approx)
