need step by step explanation clearly..

Answer 1

Explanation:

f= -15cm(concave mirror focal length is always negative)

u= -25cm

By using formula

v=uf/u-f= (-25)×(-15)/-25+15= -75/2cm

hence screen should placed 37.5 cm in front of mirror.

now linear magnification = h(image)/h(object)= -v/u

h(image)/4= -(-37.5)/-25

h(image)= -6cm

hence the image is real,inverted,magnified
