Question

The Uses of convex lenses​

Answer 1

Answer:

The convex lens is used to solve the problem of farsightedness or Hypermetropia, by bending the light ray which shortens the focal length and makes the light ray focus on the retina in a proper way. Cameras: The convex lens is used in the camera for focusing the image and also for magnifying it.

The convex lens is used to solve the problem of farsightedness or Hypermetropia, by bending the light ray which shortens the focal length and makes the light ray focus on the retina in a proper way. Cameras: The convex lens is used in the camera for focusing the image and also for magnifying it.

Some convex lens uses are listed in the points below.

• Magnifying glasses
• Eyeglasses
• Cameras
• Microscopes

A convex lens is a converging lens. Therefore when parallel light rays pass through the lens, the refracted rays converge at one point, which is called the principal focus. The angle at which the rays of light enter the convex lens depends on the distance of the object from the lens. The image formed by a convex lens is real. Some convex lens uses are described in the points given below.
