Question

State and explain the laws of reflection of light at a plane surface with the help of labeled ray diagrams. Mark angle of ‘incidence’ and ‘reflection’ clearly on the diagram. If the angle of reflection is 47.5 , what will be the angle of incidence?
​

Answer 1

Answer:

First law of reflection: According to the first law of reflection, the incidence ray, the reflected ray and the normal (at the point of incidence), all lie in the same plane. For e.g., in the figure, the incident ray AO, the reflected ray OB and the normal ON, all lie in the same plane, the plane of paper.

Answer 2

$\huge\sf {\dag Reflection }$

$\implies$ The bouncing back of light is called reflection.

$\huge\sf {\dag Laws \: of \: Reflection }$

• The incident ray , the reflected ray and the normal at the point of incidence lie in on the same plane.

• The angle of incidence is equal to the angle of reflection. [ Angle i = Angle r ]

[ Refer to the attachment for the diagram.]

If the angle of reflection is 47.5 , what will be the angle of incidence?

$\implies$ The angle of incidence will also be 47.5 because laws of reflection clearly states that angle of reflection and angle of incidence is always equal.
