A convex lens is immersed in water. Compared to its power in air, its power in water will.
A convex lens is immersed in water. Compared to its power in air, its power in water will.
The correct option is D Diminish
when convex lens is being transferred from air to water then its ability to converge rays of incident light will be reduced.
This occurs due to the relationship between the water and the lens and their respective refractive values.
Incident light passing through the lens is refracted (or bent) according to Snelle's Law and is dependent on the difference between the optical densities between the two elements that make up the interface between the lens surface and the surrounding medium. The greater the difference in optical density between the two, the greater the potential for refraction
Whilst a typical lens made from glass or plastic has the highest refractive index out of the three elements (lens, water and air), water has a higher refractive index than air and thus when the lens is immersed into the water, the refractive difference between those two elements is less than between the lens and air
