Detailed Solution

The above statement is False.
Glass has a refractive index of 1.52 and water has a refractive index of 1.33. Because glass has a higher refractive index than water, the speed of light in water is faster than that of light through glass. When the refractive index of one medium exceeds that of another, the first medium is said to be optically denser.
The correct statement would be glass has a higher refractive index than water.
