Question

an object is kept at 30 cm distance from the concave mirror of focal length 60cm. what is the position,nature and size of the image formed?​

Answer 1

Answer:

Here,

u= -30 cm

f= -20 cm

By using mirror formula,

1/v + 1/u = 1/f

1/v + 1/-30 = 1/-20

v= -60 cm

negative sign indicates that image is in front of the mirror

Therefore,

The distance between image and object = 60–30 = 30cm
