Question

What is Magnification of Terrestrial Telescope?

Answer

Magnification of Terrestrial Telescope - (a) For relaxed eye, M_∞ = f₀/f_e In this position, length of telescope L_∞ = f₀ + 4f + f_e (b) When a final image is formed at least distance of distinct vision, M₀ = f₀/f_e (1 + f_e/D) Length of telescope, L_∞ = f₀ + 4f + u_e f₀ = Focal length of objective lens f_e = Focal length of eyepiece
