Match List \(− I\) (Event) with List \(−II \) (Order of the time interval for happening of the event) and select the correct option from the options given below the lists
List \(- I\) List \(- II\)
\((1)\) Rotation period of earth \((i)\) \(10^5\, s\)
\((2)\) Revolution period of earth \((ii)\) \(10^7\, s\)
\((3)\) Period of light wave \((iii)\) \(10^{-15}\, s\)
\((4)\) Period of sound wave \((iv)\) \(10^{-3}\, s\)

  1. A \(( 1 )-(i), (2)-(ii), (3)-(iii), ( 4 )-(iv)\)
  2. B \((1 )-(ii), (2)-(i), (3)-(iv), ( 4)-(iii)\)
  3. C \((1)-(i), (2)-(ii), (3)-(iv), (4)-(iii)\)
  4. D \((1 )-(ii), (2)-(i), (3)-(iii), (4)-(iv)\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(( 1 )-(i), (2)-(ii), (3)-(iii), ( 4 )-(iv)\)

Step-by-step Solution

Detailed explanation

Rotation period of earth is about \(24\) hrs \(=\) \(10^{5} \mathrm{s}\) Revolution period of earth is about \(365\) days \(=10^{7} \mathrm{s}\) Speed of light wave \(\mathrm{C}=3 \times 10^{8} \mathrm{m} / \mathrm{s}\) Wavelength of visible light of spectrum \(\lambda\)…
