State and explain the laws of reflection of light at a plane surface (like a plane mirror), with the help of a labelled ray-diagram. It is when the brain is rewired to function in some way that differs from how it previously functioned. In this case, the object is located beyond the center of curvature (which would be two focal lengths from the mirror), and the image is located between the center of curvature and the focal point. Sign Convention for Spherical Mirrors What name is given to this type of image ? Which mirror is used as a torch reflector ? The numerical values in the solution above were rounded when written down, yet un-rounded numbers were used in all calculations. How far away from his eyes does the chart appear to be ? Concave mirror produced the magnified image while the convex mirror will produce a diminished image, Power of convex lens, P1 = 1/f1=1/0.25=+4D, Power of concave lens, P2 = 1/f2=1/ - 0.1m=-10D, power of combination, P = P1 +P2 = 4D 10D = -6D.
