How does the curvature of a concave lens affect the location of the focal point?
In a concave lens, the focal point is located on the same side as the incoming light rays. A more curved concave lens will have a shorter focal length, bringing the focal point closer to the lens surface.
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
What is formula for concave lens?
The formula for a concave lens is the same as for a convex lens, which is given by the lens formula: 1/f = 1/v + 1/u, where f is the focal length of the lens, v is the image distance, and u is the object distance. For a concave lens, the focal length is considered negative.
Why it is easier to find the focal point of convex lens than concave lens?
It is easier to find the focal point of a convex lens because the focal point is on the same side as the incoming light, making it more accessible to measure. In contrast, for a concave lens, the focal point is behind the lens and is virtual, making it harder to locate experimentally.
A concave mirror and a convex lens are held in waterwhat changes if any do you expect in their focal length?
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!

A concave lens is kept in contact with convex lens of focal length 20cm the combination works as a converging lens of focal length 100cmcalculate the power of concave lens?
i think it is -0.06m i.e. 6cm

What happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
What is the positive lens is the same as?
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.

A concave lens bends light towards its what?
A concave lens bends light away from its center, diverging the light rays.
Why doesn't a concave lens have a focal point?
because it is not refracted or reflected
