A source S_(1) produces 10^(15) photon every second having wavelength of 5000Å .Another source S_(2) produce 1.02xx10^(15) photon every second with wavelength 5100 Å product [Power of S_(1)]xx[Power of S_(2)]=….

Answer»

`1.00`
`1.02`
`1.04`
`0.98`

Solution :Energy produced every second by `S_(1)` (power)
`P_(1)=n_(1)(HC)/(lambda_(1))`
Energy produced every second by `S_(2)` (Power)
`P_(2)=n_(2)(hc)/(lambda_(2))`
`THEREFORE (P_(2))/(P_(1))=(n_(2))/(n_(1))xx(lambda_(1))/(lambda_(2))`
`=(1.02xx10^(15))/(10^(15))xx(5000)/(5100)=1.0`
