State diffrence between concave lens and convex lens?

Question

Answer

Convex:-(¡)The lens which is thick at the middle and thin at the ends is called convex lens.(¡¡)Convex lens bend inwards.(¡¡¡)They are also known as converging lens.Concave:-(¡)The lens which is thin at the middle and thick at the center is called concave lens.(¡¡)The concave lens bends outwards.(¡¡¡)They are also known as diverging lens.

Answer

Concave lens is also known as convex mirrorconvex lens is also known as concave mirror

Answer

It is thin from middle it is thick from middle

Answer

Difference between Concave Lens and Convex Lens

Concave Lens:
- A concave lens is thinner at the center and thicker at the edges.
- It causes light rays to diverge or spread out.
- It is also known as a diverging lens.
- Concave lenses are used in various optical devices like cameras, telescopes, and glasses for nearsightedness.

Convex Lens:
- A convex lens is thicker at the center and thinner at the edges.
- It causes light rays to converge or come together at a focal point.
- It is also known as a converging lens.
- Convex lenses are commonly used in magnifying glasses, microscopes, and eyeglasses for farsightedness.

Key Differences:
- Concave lenses diverge light rays, while convex lenses converge light rays.
- Concave lenses have a virtual focus point on the same side as the light source, while convex lenses have a real focus point on the opposite side of the light source.
- Concave lenses produce smaller and upright images, while convex lenses produce larger and inverted images.
- The focal length of a concave lens is negative, while the focal length of a convex lens is positive.

In conclusion, concave and convex lenses have opposite optical properties and are used in different applications based on their ability to diverge or converge light rays.
