Chapter Nine RAY OPTICS AND OPTICAL INSTRUMENTS
ncert.nic.inIn this chapter , we consider the phenomena of r eflection, r efraction and dispersion of light, using the ray picture of light. Using the basic laws of reflection and refraction, we shall study the image formation by plane and spherical r eflecting and r efracting sur faces. W e then go on to
