### Class 10 Physics Chapter 4 – Refraction of Light at Plane Surface

Below written is a brief description of ICSE Class 10 Physics Chapter 4. The ICSE Class 10 Physics Revision Notes Chapter 4 promote the understanding of the subject within the students and also provides a firm foundation before moving on to the next chapter.

As per the definition, Refraction is the bending of sunshine because it passes from one translucent substance into another (it also happens with sound, water, and other waves).

This refractory bending allows us to have lenses, magnifying glasses, prisms, and rainbows. Even this bending of light depends on our eyes. We would not be able to concentrate light on our retina without refraction.

Refraction of light happens when a light wave bends upon entering a medium where its velocity differs. When it passes from a fast medium to a slow medium, the refraction of light bends the light ray towards the normal, to the boundary between the two media. The amount of bending depends on the two media refraction indices and is quantitatively described by Snell’s Law. Students can revise all the laws of refraction, as well as their concepts using the ICSE Class 10 Physics Revision Notes Chapter 4.
