Answer 1

Answer:

rectilinear propagation I think it will help for you plz send me thanks bye bye

Answer 2

Given:

The magnification of the mirror m= 2.5

To find:

The focal length that is the point.

Solution:

Let the height of object= u

The height of image = v

Using the magnification formula

m= -v/u

2.5=-v/u or 2.5/v=-1/u

Now using the lens formula

1/f=1/v-1/u

1/f=1/v+2.5/v

1/f=3.5/v

f=v/3.5

So, the point is f=v/3.5
