Does the focal length of a converging lens change in water?
The focal length of a lens is very much affected when immersed in water. The reason is that the angle of refraction is dependent on the relative difference between the indices of refraction of the incoming medium and the medium of the lens. Your eyes’ focal length change dramatically.
When a converging lens is immersed in liquid its focal length will?
When it is immersed in a liquid it behaves as a converging lens its focal length becomes xf(x>1).
When a lens is immersed in water its focal length increases explain with an activity?
Answer Expert Verified focal length depends upon refractive index of lens with respect to medium. hence, after immersing of lens in water focal length of lens increases.
What happens to focal length of concave lens in water?
when concave lens immersed in water the focal length of lens increases because focal length of lens is directly proportional to refractive index of medium and when immersed in water the medium become more dancer so its focal length increases.
What happens when a lens is immersed in water?
Thus the overall value of the denominator on the right-hand side will decrease. Now since the focal length is inversely proportional to the (μ−1), therefore the focal length will increase. Hence the focal length of the lens increases when it is immersed in the water.
Why convex lens behaves as converging lens in air but becomes diverging when immers in liquid of refractive index greater than lens?
When a ray of light in incident on the lens parallel to the principal axis, it gets refracted and meets the principal axis at the focus. Since the refractive index is lesser, as compared to not being immersed in water, the ray of light would be deviated to a lesser extent.
When a lens is immersed in water its power?
Complete answer: When a lens is submerged in water, the focal length increases, and as focal length is inversely related to angular magnification, the power of the lens diminishes or decreases.
Does focal length of a lens change on changing image distance?
Answer: No, as focal length doesn’t depend on object distance. It depends on centre of curvature and refractive index of material used in making the lens.
Why does the focal length increase when a lens is immersed?
Yes, the focal length increases in water because there is less difference in index of refraction between glass and water than between glass and air. Thus light rays change direction less with water surrounding the glass. See: Why, when a lens is immersed in water, does its focal length increase?

What happens to a convex lens when it is immersed in water?
So you can see that the refractive index of glass with respect to water is lesser than that of glass with respect to air so the extend to which light bends when travelling from water to glass less so it seems that the power of the lense has been reduced. A convex lens is immersed in water. Will its focal length change? Yes.
Does the focal length of a concave mirror change when immersed in water?
And as we know that the laws of reflection is not affected by the surrounding medium. Therefore the focal length of concave mirror doesn’t change when it is immersed in water, though in case of lenses the focusing property of is dependend on the nature (refractive index) of the surrounding medium.

What happens to the ray of light when the lens is immersed?
If the refractive indices of water and the lens, with respect to air, are, say, 1.3333 and 1.5, when the lens is immersed in water, its refractive index with respect to water would be 1.5 1.3333 = 1.125. Since the refractive index is lesser, as compared to not being immersed in water, the ray of light would be deviated to a lesser extent.
