Q. 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 $10^{-8}, s$.

In This post you will get answer of Q.
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 $10^{-8}, s$.

Solution:

Time taken for the light emission from an atom ≈ 10-8 s.

Time taken for release of energy in fission ≈ 10-6

Required ratio $=frac{10^{-8}}{10^{-6}}=frac{1}{100}=1 : 100$
