Question

A plane mirror lies in the x-y plane with its reflecting side on the +ve side of z-axis. A point at the coordinates ( x , y , z ) has a velocity whose components along x, y and z directions are u , v and w , respectively. The coordinates of the image and its velocity components will be:

TestHub · Accepted Answer

The mirror plane is z = 0 , so only the z-coordinate changes sign. Image: ( x , y , − z ) . Velocity components parallel to the mirror stay the same: u , v . The perpendicular component reverses: − w . Image velocity = ( u , v , − w ) .
