did the flea use concave or convex lens?
Answers
Explanation:
A concave lens is used to diverge incident rays. This helps to create a virtual image on the opposite side of the refracting surface. Hence, these lenses are used in binoculars, telescopes, cameras, flashlights and eyeglasses.
Answer:
Light is a fascinating chapter included in the science syllabus. Students learn a lot of new concepts in this chapter. As they proceed to the new classes, they delve deeper into the basic and advanced concepts of light. First, they learn the features of light rays and then proceed to learn what reflection of light rays is. On proceeding further, they come to know how refraction of light rays occurs in a transparent medium. We will study the features of a concave and convex lens in this section.One of the most significant parts of this chapter is the lens. It is a transparent medium made of glass but has one or two curved surfaces. Lenses are of two types, concave and convex lenses. The nature of the curved surface determines what kind of lens it is. Studying the behaviour of the lenses will help distinguish between a concave and convex lens. Let us learn what a concave and convex lens is first.
What is a Convex Lens?
A curved transparent medium made of glass that looks like a part of a compact sphere is called a convex lens. The surface of this lens has an external curve that looks like the surface of a glass ball. When light rays fall on the convex surface of this lens, they tend to converge from their paths.
What is a concave lens?
A concave lens is a type of transparent medium made of glass that has one or two concave surfaces. The best way to recognize a concave lens is by checking the curved surface. It resembles the inner surface of a hollow sphere, almost like the mouth of a cave. These lenses are also called divergent lenses as the parallel beams incident on their surface tends to diverge from their paths.
Why Should You Differentiate Between Concave and Convex Lens?
The difference between a concave and convex lens will help you understand the traits of each lens. It will also help you figure out the adjustments in the formula used to calculate image distance, object distance and focal length of a lens.
