Question

Please answer the above question The best and the right answer will be Marked as the BRAINLIEST​

Answer 1

In mediumC

Explanation:

As there is less bending of light toward normal,so angle of refraction is more that means it is less denser.So the speed of light will be maximum in less denser medium I.e.Medium C. Mark as brainliest

Answer 2

Answer:

nA , nB and nC are refractive indices of A, B and C respectively. ;sin I= same incident angle=x;r1=10°, r2=25° and r3=40°

nA=sin I/sin r1=x/sin 10°

nB=x/sin 25°

and, nC=x/sin 40°

since, sin 10°<sin 25°<sin 40°, thus, nA>nB>nC

as, refractive index of C is the least, thus, here, speed of light will be the maximum
