Question

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?

Quantrex Academy · Accepted Answer

Correct answer: C. 3.34 ~m

Distance of jeep, x= D d 1.22 where D= diameter of lens, aligned d &= seperation between sources x &= (2 10⁻³ ) 1.2 1.22 5896 10⁻¹⁰ =3336 ~m x &=3.34 ~km aligned
