Question

Compare two quantities — Quantity A and Quantity B — and then determine which of the following statements describes the comparison:

In a lens, if
u - distance of the object from the lens
v - distance of the image from the lens
$h^i$ - height of the image
h - height of the object

• A. Quantity A is greater
• B. Quantity B is greater.
• C. The two quantities are equal.
• D. The relationship cannot be determined from the information given.

Answer 1

The correct option is C The two quantities are equal.

Lens magnification formula states that,

m = $\frac{v}{u}$ = $\frac{h^i}{h}$

therefore both the quantities A and B are equal.
