Question

3) An object is placed at 6cm in front of a concave mirror of focal length 10cm. Find the position and nature of the image.​

Answer 1

Answer:

the object is placed between the focus and the pole.

the nature of the formed image is real and inverted and smaller than the object.

Explanation:

U= -6cm and f = - 10 cm

According to formula :

1/f = 1/v-1/u

1/-10 = 1/v - 1/-6

1/v = -(1/10 - 1/6)

= - 3.75

M= height of image/ height of object = -v/u

M= - (3.75/6)

M= -0.625

it means the image is formed is real and inverted and smaller than the object.
