# A star is emitting light at the wavelength of 5000 A. Determine the limit of resolution of a telescope having an objective of diameter of 200 inch. - Physics

Sum

A star is emitting light at the wavelength of 5000 A. Determine the limit of resolution of a telescope having an objective of a diameter of 200 inch.

#### Solution

Data: λ = 5000 Å = 5 × 10-7 m

D = 200 × 2.54 cm = 5.08 m

θ = (1.22 lambda)/"D"

= (1.22 xx 5 xx 10^-7)/5.08

Concept: Diffraction of Light
