Question

A ray is incident at origin from point p(a,a.-b) find unit vector in direction of reflected ray

Answer 1

Answer:

Reflection of a ray of light is just

Explanation:

Reflection of a ray of light is just like an elastic collision of a ball with a horizontal. ... Component of incident ray along the inside normal gets reversed while the component. ... or, ˆr=-1√3(ˆi+ˆj+ˆk)hat r=-(1)/(sqrt(3))(hat i+hat j+hat k).
