## Homework Statement

Calculate the angle of deviation at a glass air interface for an angle of incidence of 65 degrees and refractive index of glass at 1.55

## Homework Equations

n1 * sin ( incidence angle ) = n2 * sin ( refractive angle )

## The Attempt at a Solution

1.55 * sin (65 ) = 1 * sin(x)

1.40 = sin(x)

sin-1(1.40) = x

BUT WAIT you can't do sin inverse of a number higher than 1 so can some one please help me

The Second problem we didn't have the slightest clue as to where to start.

2.Use the ray tracing or the formula method to determine the magnification of an object placed under the following two-lens microscope. The object is placed 5.2mm from an objective lens of focal length 5.0mm.They eye-piece lens has a focal length of 40mm. The poles of the lenses are 150mm apart.

Please Help Thanks Sinners
