A. water to air
B. water into glass
C. glass to air
D. glass into water

Correct Answer:

Option B – water into glass

Glass is denser than water because speed of light in glass is less than that of water.

Some typical refractive indices for yellow light (wavelength equal to 589 nanometres [10−9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, 1.655; and diamond, 2.417.
