The head lights of a jeep are 1.2 m apart. If the pupil of the eye of an observer has a diameter of 2 mm and light of wavelength 5896 Å is used, what should be the maximum distance of the jeep from the observer if the two head lights are just separated

A

33.9 km

B

33.9 m

C

3.39 km

D

3.39 m

Text Solution

Verified by Experts

The correct Answer is:
C
Distance of jeep from the observer
= `(D xx d )/(1.22 lambda ) = (2 xx 10^(-3) xx 1.2)/(1.22 xx 5896 xx 10^(-10))`
= 3.34 km = 3.30 (km ) (approx).
