a concave mirror produces three time magnified (enlarged) real image of an object placed at 10cm in front of it. where is the image located
Answers
Answer:
30 cm in front of the mirror.
Explanation:
U = - 10 cm
And we have , image is real and three times of object distance.
So, V= - 3 ×10 cm
V = - 30 cm
Image is located 30 cm in front of the mirror.
Hey Soul ❤
Your Answer :
Magnification produced by a spherical mirror :
m = Height of the image/Height of the object
= Image Distance/Object Distance
m = h'' / h' = - ( v / u )
Let the height of the object, h' = h
Then, height of the image, h'' = -3h
( here image distance is in minus so it should be real )
now,
-3h/h = - v/u
v/u = 3
Object distance (u)= - 10 cm { Given }
v = 3 × ( - 10 ) = - 30 cm
Therefore, the negative sign indicates that an inverted image is formed in front of the given concave mirror at a distance of 30 cm.
