Question

an object of height 5cm is kept in front of a lens . an inverted image of height 5cm is formed. identify the lens and position of the object​

Answer 1

Answer:

given

ho = 5cm = height of object

hi = -5cm = height of image

nature of lens is convex as only convex lens can form real and inverted image

and. the object is on centre of curvature

because height is object is equal to height is image formed....

Answer 2

The type of lens involved is a convex lens and the object is positioned at the center of the curvature of the convex lens.

• According to the question, a real, inverted, and same-sized image of the object is formed.
• A concave lens is a diverging lens and always forms virtual images. But convex lenses are converging lenses and are the only type of lens that produce real and inverted images of the corresponding objects.
• When an object is placed at the center of the curvature of a convex lens, its corresponding image is formed on the opposite side of the convex lens. The image formed is real and inverted.
• The distance of the image from the lens is equal to the distance of the object from the lens.
• For a convex lens, the distance of the center of curvature from the lens is double the focal length of the lens.
• That's why the convex lens and center of curvature are the correct answer to this question.
