An FM radio transmitter has a power output of 170 kW and operates at a frequency of 105.5 MHz. The total number of photons emitted per second by the transmitter will be 0.229* 10³¹.
Given that, power of the transmitter p = 160 kW = 160* 10³ W
Frequency of the transmitter = 105.5 MHz = 105.5* 10⁶ Hz
Number of photons emitted per second is given by the formula,
N = p / h * v = 160* 10³/(6.6* 10⁻³⁴ * 105.5* 10⁶) = 160* 10³¹/(696.3) = 0.229* 10³¹
Thus, the total number of photons emitted by the transmitter will be 0.229* 10³¹.
