The radius of curvature of the mirror.
Answer to Problem 15P
Solution:
The nature of mirror is concave mirror as focal length is positive and its radius of curvature is + 5.7 m.:
Explanation of Solution
Given Info:
Image is upright.
Let height of object be
Height of image
Object distance
Image distance = ‘v’
Nature of image is upright and three times of the object’s height
Let the focal length of mirror be ‘f’
Formula Used:
(i)Apply focal length formula for mirror
(ii)Magnification of mirror
Here, all alphabets are in their usual meanings.
Calculation:
Apply magnification of mirror
Apply focal length formula for mirror
Since the radius of curvature R = 2f
So, the radius of curvature R = 2 ×(+2.85 m)= + 5.7 m:
