    • So far, you have learnt about why reflection occurs and how it differs depending on the surface which the incident rays strike. Let's re-look at the image you studied earlier and define some reflection laws which it illustrates.


    • First law of reflection

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

      Second law of reflection

      The angle of incidence (i) is equal to the angle of reflection (r). 

      i = r

      These angles are calculated by comparing the angle of the incident ray to the normal line (which is perpendicular to the surface) and the angle of the reflected line compared to the normal line.

    • In closing, watch the short YouTube video below which clearly explains the concept of light reflection and its properties.
