Question

$what \: is \: angle \: of \: reflection \: means \: and \: \\ what \: is \: law \: of \: \perndicular$
​

Answer 1

Answer:

Whenever we look into a mirror, or squint at sunlight glinting from a lake, we are seeing a reflection. ... The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
