What happens when an object is placed in front of a convex lens?

A converging lens produced a virtual image when the object is placed in front of the focal point. For such a position, the image is magnified and upright, thus allowing for easier viewing.

What affects the focal length of a convex lens?

Several factors affect the focal length. So, focal length depends on the radius of curvature, the refractive index of lens material, and the medium’s refractive index in which the lens is placed. Note: Focal length is the length between the middle of the lens and the principal foci.

What happens when a concave lens is placed in water?

When kept inside water, the laws of reflections are still valid, thus the focal length of the concave mirror does not change. Since water has a greater value of refractive index than air, the converging power of the lens will be less as compared to air. Thus the focal length of the convex lens will increase.

Is the focal length of the combination of convex lens of power 1d and concave lens of power?

If convex lens of focal length f and a concave lens of power f1​ are put in contact, then the focal length of the combination is zero.

Which lens has more focal length convex or concave?

Hence, the lens with a shorter focal length will have more power or higher refraction (causes more bending of light rays). While the lens with a longer focal length will have less power or low refraction (causes less bending of light rays). Thus, a thick convex lens has more power, as it has a lesser focal length.

What happens to the focal length of a convex lens when it is kept in water?

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.

When the object is placed between convex lens and focal point then the image will be?

Same size, real and inverted.

What will happen to focal length if we keep a convex lens in water and why?

Does focal length of convex lens change in water?

Does focal length of concave lens increases in water?

Yes. Focal length changes when lens is immersed in water.
