  List-I   List-II
(a) The rotation period of earth (i) 105 s
(b) Revolution period of earth  (ii) 107 s
(c) Period of a light wave  (iii) 10-15 s
(d) Period of a sound wave  (iv) 10-3 s
  1. (a)‐(i), (b)‐(ii), (c)‐(iii), (d)‐(iv)
  2. (a)‐(ii), (b)‐(i), (c)‐(iii), (d)‐(iv)
  3. (a)‐(i), (b)‐(ii), (c)‐(iv), (d)‐(iii)
  4. (a)‐(ii), (b)‐(i), (c)‐(iv), d‐(iii)

Solution

The duration of the day 86400 s≃105 s

revolution period 365 days≃107 s

For the light of λ=6000 A0, time period≃10-15 s and

for the sound wave time period≃10-3 s
