Question

. Determine the image distance and image
height for a 5cm fall object placed 30cm
form a concave mirror having focal length
of
15cm​

Answer 1

Answer:

Image distance=-30cm

Image height=-5cm

Explanation:

ho=5cm

u=-30cm

f=-15cm

By mirror formula,

1/v+1/u=1/f

so,

1/v=1/f-1/u

=1/-15-(-1/30)

1/v=-1/30

v=-30cm

hi/ho=-v/u

hi/5=-(-30)/-30

hi=-5cm
