Wave Optics Chapter Ten WAVE OPTICS
ncert.nic.inPhysics 354 small portion of the sphere can be considered as a plane and we have what is known as a plane wave [Fig. 10.1(b)]. Now, if we know the shape of the wavefront at t = 0, then Huygens principle allows us to determine the shape of the wavefront at a later time τ. Thus, Huygens principle is essentially a geometrical construction,

Reflectance, as defined in physics and optics, is the ratio of the energy of a wave reflected from a surface to the energy possessed by the wave striking the surface. Some materials are used for mirrors
Chapter Nine RAY OPTICS AND OPTICAL INSTRUMENTS
ncert.nic.inPhysics 312 The distance between the focus F and the pole P of the mirror is called the focal length of the mirror, denoted by f.We now show that f = R/2, where R is the radius of curvature of the mirror. The geometry of reflection of an incident ray is shown in Fig. 9.4.
