Per NCERT Class 10 Physics Ch 9, what are the two laws of REFLECTION OF LIGHT?
ALight cannot reflect
B(i) The angle of incidence is equal to the angle of reflection (ii) The incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane
CAngle of incidence > angle of reflection always
DLight reflects only off white surfaces
Answer & Solution
Correct answer: B. (i) The angle of incidence is equal to the angle of reflection (ii) The incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane
Per NCERT §9.1, the two laws of reflection: angle i = angle r, and rays + normal coplanar.
