What is principle of revetsibility of light |
|
Answer» \xa0The 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, Amount of Light travelling from a medium to second medium is the reciprocal of amount of light travelling from second medium to first medium. |
