Assertion: The ratio for time taken for light emission from an atom to that for release of nuclear energy in fission is $1 : 100$ . Reason: Time taken for the light emission from an atom is of the order of $1 0^{- 8} s$ .

Options:

Answer:

Solution:

Time taken for the light emission from an atom $\approx 1 0^{- 8} s$ . Time taken for release of energy in fission $\approx 1 0^{- 6}$ Required ratio $= \frac{1 0 ^{- 8}}{1 0 ^{- 6}} = \frac{1}{100} = 1 : 100$
