Question

An object is placed before a convex lens rhe imafe formed will be

Answer 1

at infinity
beyond 2f
at 2f
between f and 2f
at f
between f and optic centre (c)
it will be virtual and erect

Answer 2

The nature of images created by the convex lens are as follows

• Object at infinity: Real, diminished, and an inverted image formed at f₂
• An object beyond 2F₁: Real, inverted, and diminished image between 2F₂ and F₂
• The object between 2F₁ and F₁: Real, inverted, and enlarged image beyond 2F₂
• At F₁: Real, inverted, and enlarged image at infinity.
• At 2F₁: Real, inverted, and same size image at 2F₂.
• The object between F₁ and O: Virtual, erect, and enlarged image between 2F₂ and F₂
