Explanation:
It is given that,
Radius of curvature of the mirror, R = 1.54 cm
(a) We have to find the focal length of the mirror. The relationship between the focal length and the radius of curvature is given by :
[tex]R=2f[/tex]
f = focal length of the mirror
[tex]f=\dfrac{1.54\ cm}{2}[/tex]
f = 0.77 cm
(b) The power of mirror is given by the reciprocal of focal length i.e.
Power, [tex]P=\dfrac{1}{f}[/tex]
P = 1.29 diopters
Hence, this is the required solution.
