Q.6. 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 (a) The rotation period of earth (b) Revolution period of earth (c) Period of a light wave (d) Period of a sound wave List-II (i) 10^5 s (ii) 10^7 s (iii) 10^-15 s (iv) 10^-3 s
- (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
- (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
- (a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)
- (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
Correct answer: (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
Solution
The correct option accurately matches the time intervals with the events: the Earth's rotation period is approximately 10^5 seconds (24 hours), the revolution period is about 10^7 seconds (one year), the period of a light wave is around 10^-15 seconds, and the period of a sound wave is about 10^-3 seconds.
