the mirror formula is.......1/f = 1/v + 1/u.

in our case u = -15cm

f = -10cm

therefore 1/-10 = 1/-15 + 1/v

1/v = 1/-10 + 1/15

v = -30

magnification formula is -v/u

.....................30/-15

the object is magnified with a factor of -2

the image formed is real inverted, magnified.

thanks for watching
