AP EAMCET · PHYSICS · Ray Optics
A ray of light travels from a medium of refractive index 2 to another medium of refractive index \(\sqrt{2}\). Total internal reflection takes place when the angle of incidence is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(80^{\circ}\)
Answer & Solution
Correct Answer
(B) \(45^{\circ}\)
Step-by-step Solution
Detailed explanation
Refractive index of first medium, \(\mu_1=2\) Refractive index of second medium, \(\mu_2=\sqrt{2}\) If \(i_C\) be the angle of incidence in the case of total internal reflection, then…
