CHANGE IN DIRECTION OF LIGHT

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Assertion (A): Scattering of light is the reflection of light from an object in all directions. Reason (R): The colour of scattered light depends on the size of scattering particles and wavelength of light.

Statement - 1 : If net force vecF acting on a system is changing in direction only, the linear momentum (vec p) of system changes in direction. Statement - 2 : In case of uniform circular motion, magnitude of linear momentum is constant but direction

Assertion : The twinkling of star is due to rcfiectiop of light Reason : The velocity of light changes while going from one medium to the other.

Which of the following statements are correct? (i) The shape of a shadow depends on the position of the source of light. (ii) A plane mirror can change the direction of light falling on it. (iii) A pinhole camera forms an erect image of an object on a screen. (iv) A shadow is formed when light passes through a transparent object .
