STATEMENT- 1 Law of reflection is applicable for all type of mirrors. STATEMENT 2 Rays which are parallel to principal axis are known as paraxial rays.

Assertion : Focal length of a spherical mirror does not depend on the material from which mirror is made but same for the lens depends on the material of lens. Reason : Law of reflection does not depend on material and surrounding medium but law of refraction depends on refractive index of the materials.

Arrange the following steps in a sequential order to verify the laws of reflection. (A) A hard , smooth surface (AB) is mounted vertically over a horizontal board on which two tubes P and Q , point towards the surface AB. (B) The tube Q is adjusted such that the listener would be able to hear the ticking sound clearly at the end away from AB. (C) The sound waves from a source , like ticking clock are directed to the surface AB through the pipe P inclined at an angle to AB . (D) By measuring the angles the tubes make with the surface AB , the laws of reflection are verified .

Statement I : Light reflected from any surface obeys the law of reflection. Statement II: Distance measured in the direction of light are taken as positive.
