Question

State three charcteristics of image formed by convex mirror of an obect placed in front of it

Answer 1

Answer:

From mirror formula ,

v=

u−f

uf

,

by sign convention , u=negative,f=positive ,

therefore , v will be positive and v will be less than both u and f , no matter what is the value of u .

Now, m=−

u(−ive)

v(+ive and<u)

<+1 (Erect and Diminished)

A virtual (as v is +ive) ,erect and diminished image is formed behind the mirror
