## Homework Statement

We have the wavelength of 550nm and the distance (d) of 0.120mm. I need to calculate the the angle q.

The diffirent parts of this questions corresponds to the diffirent order of n. a) Being n=1 b) n=5 c) n=10

Given variables;

Wavelength = 550nm = 550*10^-9m

d=0.120mm = 0.00012m

n1= 1

n2= 5

n2 = 10

## Homework Equations

The relevant equation for this is;

d*sin0 = n*Wavelength

0 = sin((n*Wavelength)/d))

## The Attempt at a Solution

I've attempted the solution to this and my real problem is that I have got no idea how to get the answer to Degrees. I'd really like to see someone do this so I can see what you do and how I should think.
