Answer:
The critical angle is
Explanation:
Snell's law is mathematically represented as
Where is the refractive index of medium 1
is the refractive index of medium 2
Now substituting for and ac which denotes the critical angle for
Making ac the subject
From the question we are told that
The is implies that ac < 90
since
Critical angle is that angle of incidence that result to a 90 degree angle of refraction
