Refraction of light - Along with its definition and examples, we need to concentrate on some of the terms like:
Reflective index, Snell’s law (law of refraction), refraction through a curved surface, total internal reflection, double refraction from a plane surface.
Also, do not ignore these - single refraction from a plane surface, the relationship between object distance & image distance refraction, and linear magnification for spherical refracting surfaces.
Distinguish between a thin lens and a standard lens. Some of the main terms related to the lens are:
Lens
Centre of curvature & radius of curvature, principal axis, optical center, principal focus, and focal length.
Prisms, optical instruments, eyes, simple microscopes, and telescopes are some topics that you can study in the end.
