What is refraction: Refraction Refraction is the

Refraction Refraction is the "bending" of light (or any electromagnetic wave) when entering a different medium. When electromagnetic waves enter a different medium the speed changes. The frequency stays the same, so the wavelength must change. This causes the waves to change direction (except when they travel directly forward): refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow. What Is Refraction? Refraction of Light is a phenomenon wherein light bends and travels from one transparent substance to another. Let’s understand this concept in-depth with an illustration. So, have you ever observed the bottom of a thick glass slab when a printed paper is kept below it? You will find that the printed matter seems to be raised. Similarly, when a pencil is partly immersed in water in a glass tumbler, it appears to be displaced from its original position at the surface ... Master refraction concepts in Physics with Vedantu.
