Question

Consider these indices of refraction: glass: 1.52; air: 1.0003; water: 1.333. Based on the refractive indices of three materials, arrange the speed of light through them in decreasing order.

Options

• The speed of light in water > the speed of light in air > the speed of light in glass.

• The speed of light in glass > the speed of light in water > the speed of light in air.

• The speed of light in air > the speed of light in water > the speed of light in glass.

• The speed of light in glass > the speed of light in air > the speed of light in water.

Answer 1

The speed of light in air > the speed of light in water > the speed of light in glass.
