Question

Linear magnification produced by a convex lens can be:; A. Less than 1 or more than 1; B. Less than 1 or equal to 1; C. More than 1 or equal to 1; D. Less than 1, equal to 1 or more than 1

Answer 1

A. less than 1 or more than 1

Answer 2

Answer:

Linear magnification which is produced by ‘the convex lens’ can be “Less than 1” or “equal to 1” or “more than 1”.

Explanation:

• This is because a convex mirror can form an image that can be equal, less than or more than the object’s size.
• In case of a real and inverted image by a convex mirror with negative magnification, the linear magnification $m=\frac{h^{\prime}}{H}$where h’ is the object height and H is the image height.
• Similarly, in case of the linear magnification of virtual and erect image with positive magnification is$m=\frac{h^{\prime}}{H}.$
