# State the Principle of reversibility of light

The principle that if a beam of light is reflected back on itself, it will traverse the same path or paths as it did before reversal.

The principle of reversibility states that light will follow exactly the same path if its direction of travel is reversed.

Hence:

Using Snell's Law,

 sin isin r = 1n2 sin rsin i = 2n1
 1n2= 1 2n1

It follows that

 1n2= 1 2n1

Sorry  ,

Using Snell's Law,

 sin isin r = 1n2 sin rsin i = 2n1
 1n2= 1 2n1

It follows that

 1n2= 1 2n1

this is the final equation.Sorry again

when light strikes any reflecting surface, then it goes in the same medium . if mirror is placed at right angle to the reflected ray then it returns in the same path from where it incident without any deviation

• -1

show that incident ray of light is parallel to the emergent ray of light when light falls obliquely on a side of a rectangular glass slab

• -4

i don't know

• -16

we can prove this by a expiriment using a glass salb

• -1

since the opposite faces or refracting surfaces are parallel incident ray and emergent ray are ll

• -10

The answer is : We know that "ANGLE i = ANGLE e"  & "ANGLE R1 = ANGLE R2". As External & internal Angles r equal. The lines are Parallel

The principle that if a beam of light is reflected back on itself, it will transverse the same path or paths as it did before reversal.

Refractive index for light going from medium 1 to medium 2 is equal to the reciprocal of refractive index for light going from medium 2 to medium 1

When light pass rarer to denser medium it refract towards normal and when light pass denser to rarer medium it refract away from the normal

When a light ray travelling from one medium to another and allowed it to strike a plane mirror placed perpendicular to it then it was found that the light ray retraces its path.This is called reversibility of light. For better sake of convinence I will send diagram of it.Thanks friends

when a light ray follows the same path after reflection or refraction is called as the principle of reversibility of light .

Light is a collection of wavelengths that are fitted to a scale called the electromagnetic spectrum.? I shall use visible light to talk about here, which is found in the center of the electromagnetic spectrum.? The visible light colors are red, orange, yellow, green, blue, indigo, and violet.? All these colors have specific wavelengths and frequencies.? When you speak of reversibility of light, it has the capability of reflecting off an object.? Sometimes, the light will travel back the same exact path it took to get to the object it reflected off of in the first place.? The light wave simply reverses itself.? You can demonstrate this by holding a flashlight in front of a plane mirror, shining it straight into the mirror and seeing the light being reflected back to the flashlight itself.? Be sure to use a plane mirror (one that is flat) and not a concave or a convex mirror.

If the path of a Ray of light is reversed after suffering a number of reflection and refraction ,it retraces its path therefore image and object position can be interchanged .The points corresponding to an object and its image are called "conjugate points".

Principle of reversibility is the law applied to rays of light which moves back towards its same path from where it comes without diversion any where .
Then we can use formula n21?n12=1
It will become n21=1/n12

Hi,
The principle of reversibility of light states that light follows the same path if the direction of the travel of light is reversed. In its simplest explanation, the principle of reversibility is a deduction of Snell's law of the refraction of light.
Hope this helps !

The principle of reversibility of light states that light follows the same path if the direction of the travel of light is reversed. If the direction of a ray of light is reversed due to reflection off a surface, then it will retrace its path.
