Question

A hang glider is flying at an altitude of "enters the pilot's eyes through a pupil that has a diameter of":________.

Answer 1

The correct answer is 0.0096m

L = 120m

D = 2.5mm

n = 1.36

If the separation between points is a, then for human eye,

x/L = (1.22lambda_{a})/(nD) x = (1.22L*lambda_{a})/(nD) = 0.024m

for the eagle's eye, D = 6.2 mm

and linear separation between just resolved points is x = (1.22L*lambda_{a})/(nD) = 0.0096m

From Rayleigh criterion, angular separation for between two points just resolved .

What is Rayleigh?

Rayleigh scattering (/reli/ RAY-lee), named after Lord Rayleigh (John William Strutt), a 19th-century British physicist, is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. The amount of scattering is inversely proportional to the fourth power of the wavelength for light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime).

Rayleigh scattering is caused by the particles' electric polarizability. A light wave's oscillating electric field acts on the charges within a particle, causing them to move at the same frequency.
