Question

(i) A converging mirror has focal length of 16 cm. An object is placed at a distance of 20
cm from it. Find the nature, position and size of the image​

Answer 1

Answer:

Image is 80 cm away from the mirror and is real and inverted and is enlarged in size.

Explanation:

Concave mirror

Focal length= -16cm

Object distance = -20cm

According to mirror formula,

1/f=1/v+1/u

1/(-16)=1/v+1/(-20)

-1/16+1/20=1/v

-20+16/320=1/v

-4/320=1/v

-1/80/1/v

v=-80cm
