Plane Mirrors

7 years ago


Answers : (1)


Perhaps our most familiar optical experience is looking into a mirror. Figure shows a point of source of light O, which we call the object, placed a distance o in front of a plane mirror. The light that falls on the mirror is represented by ray emanating from O. *at the point at which each ray strikes the mirror we construct a reflected ray, using the law of reflection. If we extend the reflected ray backward, they intersect at a point I, which we call the image of the object O. the image is the same distance behind the mirror that the object o is in front of it, which we prove below.

Images of diverging light in plane mirrors are always virtual. We know from daily experience how “real” such a virtual image appears to be and how definite is its location in the space behind the mirror, even though this space may, in fact, be occupied by a brick wall.

EXPERTS PLZ HELP ME Is the moment of inertia of disc and ring are (mr 2 )/2 and mr 2 respectively?? and if yes how can the moment of inetial of ring greater than that of disc ??
Yes, its true. The moment of inertia of a disc and a ring about an axis perpendicular to their plane are and resspectively. Here you have to notice in both the cases we are taking the mass...

See the moment of inertia is proportional to r 2, for same mass ,as the mass is concentrated more farther from the ring it will have greater moment of inertia.
