Question

image formed in concave mirror is 5 times the object height what is the value of its magnification

Answer 1

Dear Student,

$$\begin{gathered} m=\frac{h_i}{h_o} \\ Given, \\ {h}_i=5h_o \\ m=\frac{h_i}{h_o}=\frac{5h_o}{h_o}=5 \end{gathered}$$

As image can be both real or inverted so magnification can be both +5 or -5.
