Question:
A Concave Mirror Produces a two times larger image of an object placed at 15 cm in front of it...What is the Value of Magnification in this case because it is not given whether the image is Real or Virtual.... Please Answer Mam
Answer:
Consider magnification (m) = +2 (two times larger image of an object)
Also, Object – Distance = u = -15 cm
Then, Magnification (m) = - v/u
That is, 2 = - v/u
2u =- v
v = -2u
= (-2) x (-15cm) = 30 cm.
The image will be formed at a distance of 30 cm in front of concave mirror from its the pole.
