Answer:
step by step
Explanation:
A concave mirror has focal length 15 cm. At what distance should the object be
placed from the mirror so that it forms an image at 21 cm from the mirror? Also find
the magnification produced by the mirror.An object is placed at the focus of a concave mirror which has a focal length of
4 cm. At what distance is the image of that object formed? Draw the ray diagram.What is the value of magnification produced by a convex lens when an object is
kept at a distance from the pole which is twice the focal length of the lens? .What is the value of magnification produced by a convex lens when an object is
kept at a distance from the pole which is twice the focal length of the lens?(b) When a ray of light travelling in the air falls on a rectangular glass slab at an angle
of 45° with the normal to the surface, then the angle made by the refracted ray
with the normal inside the glass slab is equal to 30°
. What is the refractive index
of the glass slab?(a) What is the value of magnification produced by a convex lens when an object is
kept at a distance from the pole which is twice the focal length of the lens?
