1. The problem statement, all variables and given/known data
See figure attached for problem statement.
2. Relevant equations
3. The attempt at a solution
Using Snell's Law,
n_{1}sin(\theta_{1}) = n_{2}sin(\theta_{2})
n_{1} = \frac{n_{2}sin(\theta_{2})}{sin(\theta_{1})}
Where,
\theta_{1} = 30^{o}, \theta_{2} = 90^{o}
It gives me, n_{1} = 2 but the answer is a minimum of 1.15.
What did I do wrong/misunderstand?
