PHYSICS FORMULAS AND PRACTICE PROBLEMS

REFLECTION AT CURVED SURFACES & REFRACTION AT CURVED SURFACES: 1. Magnification : m = -v/u  or m=hi/ho 2. Mirror formula, 1/f = 1/u + 1/v 3. focal length f = R/2 4. Lens formula 1/f = 1/v - 1/u 5. Lens makers fomula :  1/f = (n-1) (1/R1 - 1/R2) 6. The relation between refractive indices of media, object distance, image distance, and radius of curvature is given by :                                      ...

A QUICK REVISION - PHYSICAL SCIENCES

Are you ready? ........... I : REFLECTION and REFRACTION AT CURVED SURFACES  1. Predict, Which mirror is used as rear view mirror ?  2. What is the unit of the power of the lens? Define one dioptre. (adsbygoogle = window.adsbygoogle || []).push({}); 3. Suppose that a person is using a concave mirror for shaving, Where should he place his face in front of the mirror? 4. Explain the refraction of light at plane surface and curved surface? When a ray of light passes from a denser medium to rarer medium which angle...
