Answer 1

Question :

What is the nature of the image formed by a concave mirror if the magnification produced by the mirror is 3 and positive.

Answer :

The nature of Image formed by a concave mirror of which magnification is 3 Dioptre is Virtual And Erect

$\rule{150}{0.5}$

Additional information :

• Focal length of concave mirror as well concave lens is always negative.

• Focal length of Convex Mirror and convex lens is always positive.

• Object distance is always taken as negative, because object is placed on the left side of mirror and lens.

• Mirror formula is $\sf{\dfrac{1}{f} \: = \: \dfrac{1}{v} \: + \: \dfrac{1}{u}}$

• Lens formula is $\sf{\dfrac{1}{f} \: = \: \dfrac{1}{v} \: - \: \dfrac{1}{u}}$

Where,

• f is focal length .
• u is object distance from mirror or lens.
• v is image distance from mirror or lens
