Question

Focal length of the concave mirror is 8cm. The object is placed at 16cm infront of the mirror. Write the postion of image and its nature.

Answer 1

Answer:

positon of image is 16cm in front of mirror  and is real and inverted .

Explanation:

since 1/f=1/v +1/u                            (1)

and here f= -8cm because object and focal length for  a mirror is always negative due to sign convention. so u= -16cm

hence putting values in (1) we get v= -16 cm which means position of image is also in front of mirror and due to which it is real and inverted.

i hope it help you all!

thank you!
