Answer 2

Answer:

Hi friend ✨

here is the answer ✨

$the \: radius \: of \: curvature \: of \: the \: spherical \\ mirror \: is \: 20 \: cm \: what \: is \: its \: focal \: length$

R = 20cm

f = R/2 = 20/2 = 10 cm

_________________________________________________________

PF = f

The focal length (f) of a spherical mirror is half the radius of curvature (R) of the mirror

F = R/2
