Question

g A communication system operating at a power of 510 W produces electromagnetic radiation with a wavelength of 10.5 cm . Calculate the number of photons produced by the system per minute.

Answer 1

Answer:

The value is  $N = 2.69 *10^{26} \ photons$

Explanation:

From the question we are told that

    The power is  $P = 510 \ W$  

    The wavelength is  $\lambda = 10.5 \ cm = 0.105 \ m$

   

Gnerally the number of photon produced is mathematically represented as

             $N = \frac{P * \lambda }{ h * c }$

Here  $h$ is the Planck's constant with a value   $h = 6.62607015 * 10^{-34} J \cdot s$

          c is the speed of light with value  $c = 3.0*10^{8 } \ m/s$

So  

             $N = \frac{ 510 * 0.105 }{ 6.62607015 * 10^{-34} * 3.0 *10^{8} }$

=>          $N = 2.69 *10^{26} \ photons$
