Answer:
34º
Explanation:
The computation of the angle of refraction in the glass for this ray is shown below:
Given that
the angle of incidence of another red ray is 65º
And, n_1 = 1
n_2 = 1.62
According to shell law
n_1 sin
_1 = n_2 sin
_r
sin
_r = 1 sin 65÷ 1.62
= 0.559
_r = sin^-1 (0.559)
= 34º

Explanation:
The "objective" (lens or mirror) is the major major major part of
the optical telescope. It's really the only part you need in order
to make a telescope (besides something to hold the objective).
You can put a piece of film or a CCD right at the focal point of
the objective lens or mirror and capture 'images' (pictures) there.
If you want to use the telescope for looking through and seeing stuff
with your eye, then you need the other major part ... the eyepiece lens.
