Answer:
A
Explanation:
According to Snell's law refractive index is the ratio of the sine of the angle of incidence to the normal to the barrier ( the normal is perpendicular to the surface of the barrier) to the ratio of the sine of refraction ( the angle of emergence from the second barrier) and also equals the ratio of the speed of light in the first barrier to the ratio of the speed of light in the second barrier.
Since there is no change in the direction of the propagation of light then the two materials must have matching indexes of refraction.
Pressure and heat. I hope this helps
