Hey guys, i have two question that me and a couple of my mates couldn't figure out for the life of us in class so i bring them here. The first one at first glance seemed fairly easy(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

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

2. Relevant equations

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

3. The attempt at a solution

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

1.40 = sin(x)

sin-1(1.40) = x

BUT WAIT you cant 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
