Question

anyone give me class 10th notes light - reflection and refraction. ​

Answer 1

Answer:

RELFECTION:-

WHEN INCIDENT RAY FALLS ON THE OPAQUE SURFACE IT GETS REFLECTION. THIS IS CALLED AS REFLECTION OF LIGHT.

HERE ANGLE OF INCIDENCE IS SAME AS ANGLE OF REFLECTION.

REFRACTION:-

WHEN LIGHT TRAVELS FROM ONE TRANSPARENT MEDIUM TO ANOTHER TRANSPARENT MEDIUM IT GETS REFRACTED. THIS IS CALLED AS REFRACTION OF LIGHT. HERE ANGLE OF INCIDENCE IS GREATER THAN ANGLE OF REFRACTION WHEN LIGHT PASSES FROM RARER MEDIUM TO DENSER MEDIUM AND VICE-VERSA.

HOPE THIS HELPS YOU
