Option “D” is the correct answer.
• Refractive index gives us an idea of how fast or how slow the light travels.
• The speed of light is signified by the medium (material) over which the light is traveling.
• Light travels quicker in a vacuum than it does travel in any other medium.
• Light deviates speed as it passes from one medium to another medium.
