A Ray of Light Traveling in the Air Enters Obliquely Into Water. Does the Light Ray Bend Towards the Normal or Away From the Normal? Why?

By K Balaji|Updated : November 7th, 2022

A ray of light traveling in the air enters obliquely into water. The ray bends towards the normal in this case.

Trace the path of the refracted ray

  1. The beam bends in this instance in the direction of normal.
  2. The refracted beam bends toward the normal when moving from an optically rarer medium to one that is optically denser, while it bends away from the normal when moving from one that is optically rarer to one that is optically denser.

Artificial Light Sources

In addition to natural sources, manmade sources can also produce light. There are three broad categories into which artificial light sources can be divided:

Incandescent Sources:

Some materials start to emit light when heated to a high degree. In the process, visible and infrared light are both created.

Example- Candle, incandescent lamp.

Luminescent Sources:

Accelerating charges in a luminous substance can result in the production of light. The process frequently involves running current through the material.

Example- Fluorescent tube light, electric bulb

Gas Discharge Sources:

Light can also be produced by transferring electricity via specific gases at very low pressure.

Example – Neon lamp, Sodium lamp.

Summary:-

A Ray of Light Traveling in the Air Enters Obliquely Into Water. Does the Light Ray Bend Towards the Normal or Away From the Normal? Why?

A light beam travelling through the air strikes the water at an angle. In this instance, the beam is bent toward the normal. The artificial light is divided as incandescent sources, luminescent sources and gas discharge sources.
