Question

What is the refractive index of water at 25◦C?

• A. 1.45
• B. 1.256
• C. 1.822
• D. 1.333

Hint:

The refractive index of water is critical for calculating light refraction in optics and laboratory experiments.

Answer 1

The Correct Option is D

The refractive index of water at room temperature (25°C) is a standard value of 1.333. This value indicates the ratio of the speed of light in a vacuum to its speed in water. It is a fundamental property used in optical experiments and calculations.
