A ray of light, travelling in medium A, is incident on plane interface of two media A and B and gets refracted into medium B. The angle of incidence is i and that of refraction is r. Graph between sin(i) and sin(r) is as shown in diagram. The correct statement among the following is

Question

A ray of light, travelling in medium A, is incident on plane interface of two media A and B and gets refracted into medium B. The angle of incidence is i and that of refraction is r. Graph between sin(i) and sin(r) is as shown in diagram. The correct statement among the following is, Speed of light in medium B is three fourth of that in medium A, Total internal reflection can take place, Refraction index of medium A is greater than that of medium B, None of these

sin i sin r = cot 3 7 = 4 3 = V A V B as going from rarer to denser no TIR can take place μ B μ A > 1 ⇒ μ B > μ A
