Problem 70GP

The Hubble Space Telescope, with an objective diameter of 2.4 m, is viewing the Moon. Estimate the minimum distance between two objects on the Moon that the Hubble can distinguish. Consider diffraction of light with wavelength 550 nm. Assume the Hubble is near the Earth.

Step-by-step solution

Step 1 of 2

Given

Diameter (D) of objective lens = 2.4 m.

Wavelength () of light.

According to the Rayleigh criterion, the critical angle of resolution:
