A convex lens is a type of lens that is thicker in the middle and thinner at the edges. It is curved outward on both sides and is commonly used in magnifying glasses, telescopes, and cameras.
A convex lens works by bending or refracting light rays that pass through it. When parallel rays of light pass through a convex lens, they converge or come together at a point called the focal point. This is what allows the lens to magnify objects.
Light refraction is the bending of light as it passes from one medium to another, such as from air to water or from air to a convex lens. This bending of light is what allows us to see objects as they appear to be in a different location than they actually are.
The main difference between convex and concave lenses is their shape. Convex lenses are thicker in the middle and thinner at the edges, while concave lenses are thinner in the middle and thicker at the edges. Additionally, convex lenses converge light rays, while concave lenses diverge them.
Convex lenses have a variety of practical applications, including in eyeglasses, magnifying glasses, cameras, telescopes, and microscopes. They are also used in the production of laser beams and in some types of projectors. Convex lenses are also used in the field of medicine for examining and treating the eye.
