Question

. A concave mirror formed an inverted
image of an object on a screen. If a
convex mirror is placed in between
the concave mirror and the screen,
how would the nature of the image
change?​

Answer 1

Step-by-step explanation:

Image is inverted so magnification ratio should be negative.

Since the object size is double so magnification ratio m=−2

now the object distance from mirror u=−12

So m=−

u

v

−2=−

−12

v

v=−24cm

image is formed at 24 cm from mirror in same direction of object.

Now be know
