If a telescope has a lens with a diameter of 60 cm, what is the shortest distance between two objects on the moon that the telescope can resolve? use 3.84 x 108 m for the distance from the earth to the moon, and 550 nm for the wavelength of the light coming from the moon.

x = 429.33 m

Explanation:

given,

diameter of telescope = 60 cm = 0.6 m

distance of moon form earth = 3.84 x 10⁸ m

wavelength of the light = 550 nm

shortest between the two object = ?

we know,

       θ = 1.12 x 10⁻⁶ rad/s

distance between two object will be equal to

       x = d θ

       x = 3.84 x 10⁸ x 1.12 x 10⁻⁶

       x = 429.33 m

show the diagram then i will answer

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)
