Answer:

The angles are related by Snell's Law of refraction.

Step-by-step explanation:

When light is incident on a medium at an angle this angle is known as angle of incidence and it undergoes refraction in the medium at an angle meaning that it deviates from it's normal path this angle of deviation measured with respect to normal is known as angle of refraction and are related by Snell's Law as under

$\mu _{air}sin(\theta _{a})=\mu _{lens}sin(\theta _{l})\\\\\therefore \frac{sin(\theta _{a})}{sin(\theta _{l})}=\mu _{lens}$
