Can you demonstrate the laws of reflection?

Answer 1

There are 2 major statements regarding the laws of reflection:-

1. The angle of incidence = angle of reflection OR theta 1 = theta 2

and

2. The incident ray, the reflected ray and the normal (line perpendicular to the plane of the mirror/ reflective surface) all lie in the same plane.

Hope this helps.

Answer 2

Laws of reflection

An example of the law of reflection

Main article: Specular reflection

If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection. The laws of reflection are as follows:

The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.

The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.

The reflected ray and the incident ray are on the opposite sides of the normal.

Refraction is the change in direction of a wave due to a change in its medium. It is essentially a surface phenomenon. The phenomenon is mainly in governance to the law of conservation of energy and momentum. Due to change of medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth. Refraction is described by Snell's law, which states that for a given pair of media and a wave with a single frequency, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equivalent to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the opposite ratio of the indices of refraction (n2 / n1):

Answer 3

Actually there are two laws.

First one is not usually understood by many of us.

Second one is very easy to understand. That states that the angle of incidence and angle of reflection are equal.

In the first law, we get the statement as

" the incident ray, the reflected ray and the normal drawn to the reflecting surface all the three lie in the same plane"

This could be realized only by those who are able to imagine the three dimensional view

Answer 4

To prove the law of reflection, you'll need a ray of light, maybe from a flashlight, some white paper, and a mirror. First, you'd lay some white paper on a table, so you'll see the flashlight's beam of light being relected. If someone can hold a mirror facing upside-down about 3 feet above the table while you're pointing the turned-on flashlight upward at the mirror at any angle, you should be able to see the light bouncing from the mirror at the same angle by looking at the white paper, but on the other side of the mirror. See the related link for more details.

Answer 5

laws of reflection are:

1.the incident ray the reflected ray &the normal to the surface at the point of contact are all in the same plane.

2.angle of incidence is equal to angle of reflection

Answer 6

Angle of incidence is always equal to the angle of reflection

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