Question

.The real image of an object at a distance of 80 cm from
a concave mirror of focal length 50 cm is formed at
160 cm. If the height of the object is 10cm, what is the height
of the image ?​

Answer 1

Answer:

here,

u(distance of object from mirror)=-80cm

v(distance of image from mirror)= -160cm

focal length = -50 cm

length or height of object= 10cm

according to formula

height of image(I)/height of object (O) = v/u

I/10= -160/-80

I = 2×10

I= 20 cm
