Concave mirror
R = 40 cm → f = 20 cm
M = - 4 times (maya)
S = __?
Distance of objects
M = f / (s - f)
-4 = 20 / (s - 20)
S - 20 = -5
S = 15 cm
Shadow distance
S '= m s
= (-4) · 15
= - 60 cm
R = 40 cm → f = 20 cm
M = - 4 times (maya)
S = __?
Distance of objects
M = f / (s - f)
-4 = 20 / (s - 20)
S - 20 = -5
S = 15 cm
Shadow distance
S '= m s
= (-4) · 15
= - 60 cm
no radiua of curvature is given
its in book of ncert]
incomplete qn
then how one can solve it

Objects distance u = 25cm behind the mirror
Image distance = v= 100cm behind the mirror
Image distance = v= 100cm behind the mirror
