Question

1) Find the distance of image when an object is placed on the central axis, at a Distance in front of a concave mirror whose radius of curvature is 8 cm ​

Answer 1

Answer:

Radius of curvature Ⓡ = 8 cm Focal length f = R / 2 = 8/2 = 4 cm Object distance (u) = 10 cm Image distance (v) =? We know that mirror formula 1 / f = 1 / u + 1/5 1/4 = 1/10 + 1 / v => 1 / v = 1/4 - 1/10 = 5-2 / 20 = 3/20 y = 20/3 cm ====> Hope it helps you !!
