Question

For an object placed at a distance of 20cm from the pole of a mirror, an image is formed

40cm farther from the object on the same side.
Q) draw the ray diagram for the image formed ​

Answer 1

Explanation:

$\huge\underline\mathfrak{\pink{AnsWeR }}$

1. We have, u= -20cm

As image formed at same side, so v= -40cm

Using morror formula, 1/f = 1/v + 1/u

1/f = (1/-40) + (1/-20)

1/f = (-1-2/40)

=(-3/40)

f = -40/3 = -13.34

focal length is 13.34cm

• 2.Image is formed at same side of mirror, so image is real.

• 3.Negative sign of focal length indicates the mirror is concave.

$\bf\huge{Question:-}$

For an object placed at a distance of 20cm from the pole of a mirror, an image is formed

40cm farther from the object on the same side.

Q) draw the ray diagram for the image formed

$\bf\huge{answer:-}$

As image formed at same side, so v= -40cm

Using morror formula, 1/f = 1/v + 1/u

1/f = (1/-40) + (1/-20)

1/f = (-1-2/40)

=(-3/40)

f = -40/3 = -13.34

focal length is 13.34cm

2.Image is formed at same side of mirror, so image is real.

3.Negative sign of focal length indicates the mirror is concave.
