A bi-convex lens is a type of lens that is curved on both sides, with a thicker middle and thinner edges. This shape allows it to refract light rays and form real and inverted images.
A bi-convex lens works by bending the light rays that pass through it, causing them to converge at a point on the other side of the lens. This convergence creates a real and inverted image of the object being viewed.
The quality of the image formed by a bi-convex lens can be affected by several factors, including the curvature and thickness of the lens, the distance between the lens and the object, and the wavelength of the light passing through the lens.
Bi-convex lenses have a wide range of applications in areas such as photography, microscopy, and vision correction. They are also commonly used in telescopes and magnifying glasses.
The focal length of a bi-convex lens determines the distance at which the image will be in focus. A shorter focal length will result in a larger image, while a longer focal length will create a smaller image. The focal length also affects the magnification of the image.
