Answer:
The magnification is 0.3
Explanation:
Given:
The focal length of the convex mirror, f = 15 cm
for convex mirror f = -f = -15 cm
The distance of object, u = 35 cm
Height of the object, h = 2 cm
Now, using the mirror formula, we have
where, v is the distance of the image
on substituting the values, we get
or
or
v = -10.5 cm
now, the magnification (m) is given as:
m =
on substituting the values, we get
m =
or
m = 0.3
Hence, the magnification is 0.3
