Match List $‐ I$ (Event) with List $‐ II$ (Order of the time interval for the happening of the event) and select the correct option from the options given below the lists.

	List-I		List-II
$(a)$	The rotation period of earth	$(i)$	$10^{5} s$
$(b)$	Revolution period of earth	$(ii)$	$10^{7} s$
$(c)$	Period of a light wave	$(iii)$	$10^{- 15} s$
$(d)$	Period of a sound wave	$(iv)$	$10^{- 3} s$

Options:

Answer:

Solution:

The duration of the day $86400 s ≃ 10^{5} s$

revolution period $365 days ≃ 10^{7} s$

For the light of $λ = 6000$ $A^{0}$ , time period $≃ 1 0^{- 15} s$ and

for the sound wave time period $≃ 1 0^{- 3} s$
