Light rays travelling parallel to principal axis of a convex lens after refraction meet at a point on principal axis which is called

Directions(6-8): Study the following information carefully and answer the given questions. Point D is 14 m towards the West of Point A. Point B is 4 m towards the South of point D. Point

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through centre of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of

After refraction by lens, ray parallel to principal axis passes through

After reflection from a concave mirror, rays of light parallel to principal axis converge to a point which is called

For a converging lens, a light ray that is travelling parallel to the principal axis refracts

A convex lens has a focal length of 30 cm. Calculate at what distance should the object be placed from the lens so that it forms an image at 60 cm on the other side of the lens

Lens which causes incident parallel rays of light to diverge at a point is called
