light reflection and refraction a spherical mirror produces an image of magnification -1 on a screen placed at a distance of 50 cm from the mirror the image formed is real because magnification is negative therefore the type of mirror used as a concave mirror
ii)the distance of image from the object is 0 a real and inverted image of the same size is formed at same place where object is placed.
iii) periodical mirror has a radius of curvature R and the focal length that is F=R/2 ,F=50/2,F=25 cm
iv)figure attached show the image formation by concave mirror for the given case
sorry I am unable to show the figure of the concave mirror for the given case.
