Question

how can it be solved​

Answer 1

.•♫•Hola dear •♫•.

energy emitted per second ,

p= 10/100×60

= 6 js ^-s

now let n is equal to number of photon emitted per second .

therefore , energy emitted per second

= nhv = n hc/ lemda

p= nhc/ lemda

n= P lemda / hc

= 6 × 5600 × 10^-10 / 6 .6 × 10^-34 × 3× 10^8

= 1.69 × 10^19
