Question

if you stand 20cm in front of a convex mirror radius of curvature 20cm. where will the image be formed write down the nature of image formed draw the ray diagram​

Answer 1

Answer:

15 CM

Explanation:

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

P = ? (Distance of the object)

q =2p (from definition of magnification)

Formula for concave mirror is

1/f = 1/p + 1/q

1/f = 1/p + 1/2p

1/f = 3/2p

P = 3f/2 =(3×10cm)/2

P = 15cm

Answer 2

Answer:

the first answer is right
