Do the rays reflected from the plane mirror obey the Law of Reflection? Explain.

Expert Solution

Law of reflection :-

1) Reflected ray lies in the plane formed by incident ray and the normal drawn at the point of incident; and the two rays are on both side of normal.

2) Angle of incident is equal to angle of reflection.

Reflection of light from the plane mirror :-

As you can see in above diagram light ray incident on a plane mirror and get reflected back in the same medium.

As shown in diagram both incident and reflected ray are lies in the same plane and both rays are on both side (opposite side ) of normal.

Aslo incident ray AB is making angle with the normal N and reflected ray BC also making same angle with the normal N. practically if we measure both angle of incident and angle of reflection we will found that both angle are same.

Hence from above point we can say that the rays reflected from the plane mirror obey the Law of Reflection.

Trace the path of a ray emitted from the tip of the object toward the focal point of the mirror and then the reflected ray that results. Start by extending the existing ray emitted from the tip of the object. Then create the reflected ray. Draw the vector for the reflected ray starting from the point where the incident focal ray hits the mirror. The location and orientation of the vector will be graded. The length of the vector will...

Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the...

6.4.2: ENGINEERING / ACOUSTICS: For plane wave reflection from a fluid-fluid interface it is observed that at normal incidence the pressure amplitude of the reflected wave is one-half that of the incident wave (no phase information is recorded). As the angle of incidence is increased, the amplitude of the reflected wave first decreases to zero and then increases until at 30˚ the reflected wave is as strong as the incident wave. Find the density and sound speed in the second...
