QAIPMT-2010-Ph-2054: NEET 2010 Physics - Class 12 AIPMT-2010-Ph-2054 Solution: A source \(S_1\) is producing \(10^{15}\) photons per second of …

A source

S_1

is producing

10^{15}

photons per second of wavelength 5000

\text{\AA}

. Another source

S_2

is producing

1.02\times10^{15}

photons per second of wavelength 5100

\text{\AA}

. Then, (power of

S_2

)/(power of

S_1

) is equal to

Step-by-Step Verified Solution

Power of S 2 Power of S 1 = n 2 [ h c _ 2 ] n 1 [ h c _ 1 ] = n 2 _ 1 n 1 _ 2 = 1.02 _ 10 15 _ 5000 10 15 _ 5100 = 1
