Question

write down the characteristics of the convex lens? ​

Answer 1

Explanation:

The edges are curved outward rather than inward. It is used in front of the eye bends the incoming light sharply so the focal point shortens and the light focuses properly on the retina. Generally, a convex lens can converge a beam of parallel rays to a point on the other side of the lens.

Answer 2

Answer:

• When an object is placed at infinity, the real image is formed at the focus. The size of the image is much smaller than that of the object.
• When an object is placed behind the center of curvature, the real image is formed between the center of curvature and focus. The size of the image is the same as compared to that of the object.
• When an object is at the center of curvature, the real image is formed at the other center of curvature. The size of the image is the same as compared to that of the object.
• When an object is placed in between the center of curvature and focus, the real image is formed behind the center of curvature. The size of the image is smaller than that of the object.
• When an object is placed at the focus, a real image is formed at infinity. The size of the image is much larger than that of the object.
• When an object is placed in between focus and pole, a virtual image is formed. The size of the image is larger than that of the object.
