Given data:
- Magnification (M) = 3
- Object distance (u) = -10 cm (negative sign indicates the object is placed in front of the mirror)
Formula for magnification:
M = -v/u
Calculating image distance:
Given M = 3, we can rearrange the formula to find the image distance (v).
3 = -v/(-10)
v = -30 cm
Calculating focal length:
Using the mirror formula: 1/f = 1/v + 1/u
1/f = 1/(-30) + 1/(-10)
1/f = -1/30 - 1/10
1/f = -4/30
f = -7.5 cm
Calculating radius of curvature:
The radius of curvature (R) is twice the focal length of the mirror.
R = 2*(-7.5) = -15 cm
Therefore, the radius of curvature of the concave mirror is -15 cm. The negative sign indicates that the mirror is concave.
