The light when enters the human eye experiences most of the refraction while passing through
Text Solution
Verified by ExpertsThe correct answer is:
A
When light enters the human eye, it encounters different media which have varying refractive indices.
Step 1: The first medium it encounters is the cornea, which has a much higher refractive index than air (approximately 1.376).
Step 2: The cornea is primarily responsible for bending (refracting) the light as it enters the eye. It does about 70% of the eye's total optical power.
Step 3: While the aqueous humour, vitreous humour, and crystalline lens also contribute to refraction, their contributions are relatively less significant compared to that of the cornea.
Therefore, the correct answer is the cornea, making option A the most appropriate.
