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

The value is
`N = 2.69 *10^(26) \ photons`

Step-by-step 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 = (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 = ( 510 * 0.105 )/( 6.62607015 * 10^(-34) * 3.0 *10^(8) )`

=>
`N = 2.69 *10^(26) \ photons`
