Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

Question

Light is incident on a heavy glass slab of refractive index 1.6. The speed of light in the glass is

		A) 3.0 x 10⁸m/s.
		B) 2.5 x 10⁸ m/s.
		C) 1.88 x 10⁸ m/s.
		D) 1.5 x 10^-⁸ m/s.

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
