Explanation:
From the question we are told that
The power output from the sun is 
The average wavelength of each photon is 
Generally the energy of each photon emitted is mathematically represented as

Here h is the Plank's constant with value 
c is the speed of light with value 
So
=>
Generally the number of photons emitted by the Sun in a second is mathematically represented as

=> 
=>
