why is emergent ray parallel to incident ray ?
define centre of curvature of a lens.
The field of view is maximum for ____ mirror . ( concave / convex / plane )
State the rules of image formation by lenses.What is the nature (real or virtual), and size of the image formed by a convex lens when 1) the object is at 2F1 2) the object is placed between F1 and 2F1?
What is the principle of reversibility of light?
sign convenctions in spherical mirror and lens (concave & convex)
1. As we come down to the surface of earth from a distant star, how does the refractive index vary?
why does a parting in our hair on the left appear to be a parting on the right hand when seen in a mirror
describe an activity to determine the principal focus and rough focal length of a concave mirror
why dont we get a spectrum through a rectangular glass slab even on passing white light through it??
In what way yhe word AMBULANCE is
what can we do after 10th standard
sin i/sin r= constant what is constant here
question- primary function of crystalline lens in human eye is to
1) reduce intensity of light
2) adjust eye of pupil
3) ffocus incidet light rays
4) filter out dust particles
