Question

find the position of the image of a candle flaws located 40cm in front of a concave mirror of radius of convature 64cm​

Answer 1

Step-by-step explanation:

Given that,

Object distance, u = -40 cm (negative for concave mirror)

The radius of curvature of the mirror, R = 64 cm

Radius of curvature = 2(Focal length)

f = -32 cm (negative for concave mirror)

Using mirror's formula,

`(1)/(v)+(1)/(u)=(1)/(f)\\\\(1)/(v)=(1)/(f)-(1)/(u)\\\\(1)/(v)=(1)/((-32))-(1)/((-40))\\\\v=-160\ cm`

So, the image will form at a distance of 160 cm from the mirror.
