Question

the height of an object is 5 cm if the object is placed at 10 cm in front of concave lens of focal length 10 cm find the height of the image​

Answer 1

Step-by-step explanation:

h= 5cm

u= -10 cm

f= - 10cm

1/v - 1/u = 1/f

1/v = 1/f + 1/u

= 1/-10 + 1/-10

= 1/-10 - 1/10

= -1 - 1/10

= -2/10

v = -5 cm

m = hi/h = v/u

= hi = v(h)/u

hi= -5 (5)/-10

hi= -25/-10

hi = 2.5 cm
