Physics: The headlights of a car are 1.6 m apart and produce light of wavelength 575 nm in vacuum. the pupil of the eye of the observer has a diameter of 4.0 mm and a refractive index of 1.4. what is the maximum distance from the observer that the two headlights can be distinguished?

To solve this problem it is necessary to apply the concepts related to angular resolution, for which it is necessary that the angle is

$\theta = 1.22\frac{\lambda}{nd}$

Where

d = Diameter of the eye

n = Index of refraction

D = Distance between head lights

$\lambda$ = Wavelength

Replacing with our values we have that

$\theta = 1.22 \frac{(1.22)(575*10{-9})}{1.4(4*10^{-3})}$

$\theta = 1.252*10^{-4}rad$

Using the proportion of the arc length we have to

$L = \frac{D}{\theta}$

Where L is the maximum distance, therefore

$L = \frac{1.6}{1.252*10^{-4}}$

L = 12.77km

Therefore the maximum distance from the observer that the two headlights can be distinguished is 12.77km

Physics

Particles in agas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Explanation:

hope this helps
