The distance of moon form the earth is `3.8xx10^(5)` km. Supposing that the eye is most sensitive to the ight of wavelength 550nm, the separation of two points on the moon that can be resolved by a 500cm

A

50m

B

55m

C

51m

D

60m

Text Solution

Verified by Experts

The correct Answer is:
B
Resolving power=`(D)/(1.22lamda)`
Given, `D=3.8xx10^(5)kmm=3.8xx10^(8)m `
`lambda=550cm=550xx10^(9)m`
`Rightarrow` Resolving power= `(3.8xx10^(8))/(1.22xx550xx10^(9))approx55m`
