About The Human Eye and the Colourful World

This quiz covers Chapter 2 of CBSE Class 10 Physics, The Human Eye and the Colourful World.

It opens with the parts of the human eye, like the cornea, iris, pupil, lens, and retina, and how the eye changes focus using its power of accommodation. It then covers the three common eye defects, myopia, hypermetropia, and presbyopia, what causes each one, and which type of lens corrects each one.

The quiz then moves to how a prism bends light and splits it into a rainbow of colours, called dispersion, before covering atmospheric refraction, which explains why stars twinkle and why the sun looks flattened at sunset.

It closes with the scattering of light, including the Tyndall effect, and the reason behind two everyday sights: why the sky looks blue, and why the sun looks red at sunrise and sunset.

Every question comes with a clear, simple explanation, so incorrect answers become as instructive as correct ones, whether you are revising for a school test or a board exam.
