General Science Solution
Reflection of Light
(1) (i) The perpendicular to the mirror at the incidence is called normal.
(ii) The reflection of light from a wooden surface is irregular reflection.
(iii) The working of Kaleidoscope is based on the properties of reflection of light.
(4) The reflection of light from a plane and smooth surface is called regular reflection. And reflection from a rough surface is called irregular reflection.
(6) First time, the water was still, so the surface was smooth and their body reflected in the same direction and they could see their images clearly.
And when Yash threw a stone in the water, the water surface become rough, and their body reflected irregular. So, they could not see their body reflection.
Angle between the plane mirror and the incident ray is 400
Since, <COX= 900
So, <AOX= 900-400= 500
Similarly <BOX= 500
Angle of incidence and reflection is 500.
Given, <AOC= 230
Since <COX= 900
So <AOX= 900-230= 67
Angle of incidence of incident ray is 670.
