convex lens

1. (AS
b) the distance of virtual image is not greater than the object distance for convex
lens
c) convex lens always forms a real image
d) convex lens always forms a virtual image​

Answer 1

Answer:

In convex lens the virtual image is on the same side of the lens as the object and is farther away from the lens than the object.

Plane mirrors, convex mirrors, and diverging lenses can never produce a real image.

Answer 2

The correct answer is option (b) The distance of the virtual image is not greater than the object distance for a convex lens.

Explanation-

• In a convex lens, a virtual image is formed when the object is placed between the focal point and the optical center of the lens.
• The image formed is enlarged and on the same side as the object.
• Since we know that the values at the left of the central axis are always negative.
• The image formed is far left from that of the object.
• So, the distance of the image is smaller in value than the value of the distance of the object.
• In a convex lens, the nature of the image depends upon the position of the object
• A Real image is formed when the object is placed at infinity, the center of curvature, beyond the center of curvature, at focus, or between the center of curvature or focus.
• A virtual image is formed when the object is placed between the focus and optical center of a convex lens.

Hence, only option (b) is correct.
