| 2. What are the properties of a concave lens? | |
Ans. Some properties of a concave lens include:
- It is thinner at the center and thicker at the edges.
- It causes light rays to diverge.
- It forms virtual, erect, and diminished images.
- It is used in correcting myopia (nearsightedness).

Ans. Some properties of a convex lens include:
- It is thicker at the center and thinner at the edges.
- It causes light rays to converge.
- It forms real, inverted, and magnified images.

Ans. Concave lenses are used in various applications, including:
- Corrective eyeglasses for nearsightedness.
- Magnifying glasses.
- Telescopes.
Convex lenses are used in various applications, including:

| 5. How do concave and convex lenses work together in a human eye? | |
Ans. The human eye uses a combination of concave and convex lenses to focus light on the retina. The cornea, which is convex, helps in converging the light, while the lens, which is also convex, further focuses it. The lens then changes its shape to adjust the focus according to the distance of the object being viewed. This combination of lenses enables clear vision at different distances.
