Answer 1

Answer:

sorry don't know the answer

Answer 2

Answer:

Option(A) virtual,erect and enlarged

Explanation:

• When an object is positioned between a convex lens' principal focus ($F1$) and optical center (O), a virtual, erect, and enlarged image is created on the same side of the lens.

• These two refracted rays when extended backwards appear to meet behind the lens.

• Thus, a virtual image is formed.

• Concave mirrors never produce erect images at the same side of an item, and neither do convex mirrors and concave lenses.

• Convex lenses are used in eyeglasses to treat farsightedness, a condition where the retina and lens of the eye are too close together and the focal point is behind the retina.
