Diverging lens.
A Concave lens is also known as Diverging lens as it diverges the rays after they pass through its focus, whereas convex lenses are converging lens as they bend the rays after they pass through focus.
What is the another name of convex and concave lens?
A convex lens is also known as a converging lens whereas a concave lens is also known as a diverging lens.
What are the other name of convex lens?
converging lens
Explanation: – The convex lens is also known as the converging lens as it converges the light falling on it.
What is the other name for concave lens and concave mirror?
Answer: Concave mirrors are also called converging mirrors. Convex mirrors are also called curved mirror.
What are alternate names for concave and convex lenses Why are they appropriate?
Convex lenses are also called converging lenses because they refract parallel rays so that they meet at a point. What is an alternate name for concave lenses? Why is it appropriate? Concave lenses are also called diverging lenses because rays passing through them spread out.
What are the different types of concave lens?
Concave lenses are broadly categorized into the following types.
- Plano-Concave Lens. Plano concave lens has one surface curved inward, and the other surface is flat.
- Biconcave Lens.
- Convex-Concave Lens.
- Object at a Finite Distance.
- Spectacles.
- Peepholes.
- Telescopes.
- Laser Devices.
What is the other name for diverging lens?
concave lens
Also known as divergent lens, negative lens, concave lens or dispersive lens. A lens that causes parallel light rays to spread out – hence diverge – away from the optical axis once exiting the lens.
What is the other name of convex mirror?
A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source.
What is concave convex lens?
Lenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens.
Why is concave lens is also known as diverging lens?
Concave lens is called a diverging lens. The working of the lens is dependent on the refraction of the light rays as they pass through the lens. A light ray entering a concave lens diverges making the lens act like a diverging lens.Concave lens is thinner in the middle and thicker at the edges.
Which describe a concave lens?
A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
Why is a concave lens called a negative lens?
Short answer : concave lens is also called as negative lens because of its negative focal length nature.
What is the other term for a concave mirror?
Concave mirrors are also called converging mirrors. They are curved mirrors. The reflecting surface is shaped like the outside of a sphere.
What is convex and concave mirror?
Spherical mirrors whose inner side is reflecting are called concave mirrors. Spherical mirrors whose outer side is reflecting are called convex mirrors.
What is difference between concave and convex mirror?
A concave mirror is a spherical mirror with an inwardly curved reflection surface, whereas a convex mirror is a spherical mirror with an outwardly bulged reflecting surface.
How is a convex lens similar to a concave mirror?
A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror.
What is difference between convex and concave?
Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).
What are the three types of concave lens?
Types of concave lens : Biconcave lens, plano-concave lens, convexo-concave lens.
