Part (a) To Determine:
About the type of mirror.
Answer to Problem 21P
Solution:
The nature of the mirror will be concave:
Explanation of Solution
Given Info:
Magnification of the mirror ‘m’ = +1.40
Object distance
Let height of object be and height of image be
Let the image distance be ‘v’
Let the focal length of mirror be ‘f’
Formula Used:
Magnification of mirror
Here, all alphabets are in their usual meanings.
Calculation:
Since the magnification of the mirror is positive. Hence the given mirror will be concave:
Part (b) To Determine:
The nature of the image.
Answer to Problem 21P
Solution:
The nature of the image will be upright, magnified, virtual and formed behind the mirror.:
Explanation of Solution
Given Info:
Magnification of the mirror ‘m’ = +1.40
Object distance
Let height of object be and height of image be
Let the image distance be ‘v’
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
Again, apply magnification of mirror
From equation (i)and (ii), we can conclude that the image will be upright, magnified, virtual and formed behind the mirror.:
Part (c) To Determine:
The radius of the curvature of the mirror.
Answer to Problem 21P
Solution:
The radius of the curvature of the mirror will be 1.4 m.
Explanation of Solution
Given Info:
Magnification of the mirror ‘m’ = +1.40
Object distance
Let height of object be and height of image be
Let the image distance be ‘v’
Let the focal length of mirror be ‘f’
Formula Used:
(i)Apply focal length formula for mirror
Here, all alphabets are in their usual meanings.
Calculation:
Apply focal length formula for mirror
Since the radius of curvature R = 2f
So, the radius of curvature R = 2 ?— (+70.0 cm)= + 1.4 m
