Calculate the refractive index of the material ... - JAMB Physics 2002 Question

Here's how to calculate the refractive index:

1. Identify the angle of incidence and angle of refraction:

   • The angle of incidence (i) is the angle between the incident ray and the normal, which is 45 degrees.
   • The angle of refraction (r) is the angle between the refracted ray and the normal, which is 30 degrees.

2. Apply Snell's Law: Snell's law states: n1 * sin(θ1) = n2 * sin(θ2), where:

   • n1 is the refractive index of the first medium (air, which is approximately 1).
   • θ1 is the angle of incidence (45 degrees).
   • n2 is
