Question

a is placed at a distance of 20 in front of concave mirror of focal length 10 cm the image is puoduced​

Answer 1

Answer:

Here, u = - 20 cm, f = - 10 cm

According to the equation of spherical mirror,

1v+1u=1f1v+1u=1f

or, 1v+1−20=−110or, 1v+1-20=-110

or, 1v=120−110=1−220=−120or, 1v=120-110=1-220=-120

or, v=−20cmor, v=-20cm

∴∴ The image will be formed in front of the concave mirror at a distance of 20 cm.
