formula of relative refractive index
speed of light in med1/ speed of light in med 2
rules of refraction
r d t d r a
in convex lens when object is at infinity....image will be at
focus, point size, real
in convex lens when object is at 2f, image will be at
2f, same size, real, inverted
in convex lens when object is between f and o, image will be
in same side, virtual, erect, magnified
use of convex lens
microscopes, specs
define despersion
splitting of white light
in convex lens, object between 2f and f, image will be at
beyond 2f
how is speed of light and optical density related?
inversely proportional
define refraction
obliquely, bending, two medium
why do we get violet near the base in despersion
maximum bending, least speed
