A telescope consists of two lenses of focal lengths `0.3 m and 3 cm` respectively. It is fucussed on moon which subtends an angle of `0.5^@` at the obejctive. Calculate the angle subtended at the eye by the final image in normal adjustment of the telescope.

Answer

`5^(@)`

Explanation

Here, `f_(0) = 0.3 m` and `f_(e) = 3 cm, alpha = -0.5^(@), beta = ?`
Use `(beta)/(alpha) = (f_(0))/(f_(e))`
