Ever wonder why certain things are visible to us? Light is the answer to the query. Sunlight aids in our ability to see items during the day. An item reflects light when it hits it. When this reflected light reaches our eyes, it aids in our ability to see. Light is responsible for many amazing occurrences, like the birth of stars and rainbows, among many others. Let’s examine the phenomena of refraction and reflection utilising the straight-line propagation of light in NCERT Solutions Class 10 Science chapter 10 (The Human Eye and the Colourful World). In this chapter, we will also attempt to comprehend how spherical mirrors reflect light by utilising the NCERT Solutions from Bhautik Study.
