Answer:
Explanation:
f a concave mirror produces a 3 times enlarged image of an object placed 10cm in front of it, how do you calculate the radius of the curvature?
Concave mirror, hence enlarged image could mean virtual/ real both
Connotations used-
u is object distance
v is imagine distance
f is focal length
r is radius of curvature
Therefore
m=+-3
Case 1
m=3 Therefore -v/u =3
Therefore v=-3u
Given
u=-10cm
Therefore v=-3u=30cm
As we know ,mirror formula
1/v +1/u = 1/f
Therefore 1/f= 1/-10+ 1/30
By applying mathematical methods
1/f= -2/30
Therefore focal length of mirror is -15cm
Hence..we need not check case 2 since focal length of a concave mirror is always negative..so our case proves right
f=r/2
Therefore
r=2f
Hence r=-30cm
Radius of curvature is -30cm
