Question:medium

Snell's law states that (\(n_1\) is the index of refraction of the first medium and \(n_2\) is that of second, \(\theta_t\) is the angle of refraction and \(\theta_i\) is angle of incidence)

Show Hint

Snell's Law: \[ n_1\sin\theta_i = n_2\sin\theta_t \] It governs refraction of electromagnetic waves.

  • \(n_1\sin\theta_i=0\)
  • \(n_2\sin\theta_t=0\)
  • \(n_2\sin\theta_t=n_1\sin\theta_i\)
  • \(n_2\sin\theta_t=-n_1\sin\theta_i\)
Show Solution

The Correct Option is C
