Dear Students,

In Ch#12-Geometrical Optics, we will study about the terms used in reflection including normal, angle of incidence, angle of reflection, state laws of reflection, solve problems of image location by spherical mirrors by using mirror formula, define the terms ‘angle of incidence (i)’ and ‘angle of refraction (r), state laws of refractions, demonstrate the passage of light through parallel-sided transparent material, solve problems by using different formulae (i) sin ∠ i / sin ∠ r (ii) speed of light in vacuum / speed of light in the given medium (iii) real depth / apparent depth, demonstrate the passage of light through a glass prism, state the conditions necessary for total internal reflection, describe the use of total internal reflection in light propagation, describe the relation between critical angle and refractive index, demonstrate that light is refracted through lenses, solve problems of image location by lenses using lens formula, define power of a lens and state its unit, define the terms resolving power and magnifying power, draw a ray diagram of a simple microscope and determine its magnifying power, draw a ray diagram of a compound microscope and mention its magnifying power, draw a ray diagram of a telescope and mention its magnifying power, draw ray diagrams to show the formation of images in the normal eye, a short-sighted eye and a long-sighted eye and describe the correction of short-sightedness and long-sightedness. The Long Questions / Notes against this chapter are given below:
