प्रावस्था किसे कहते हैं?​

Answer 1

Answer:

भौतिक विज्ञानों में प्रावस्था (phase) से तात्पर्य किसी ऊष्मागतिकीय प्रणाली के उस प्रक्षेत्र से है जिसमें पदार्थ के सभी भौतिक गुण अपरिवर्तित रहते हैं। घनत्व, परावर्तन गुणांक, रासायनिक संरचना आदि भौतिक गुणों के अन्तर्गत आते हैं। .

Answer 2

In physics the phase is defined as the position of point at a time on a waveform cycle . A complete cycle is defined as 360 degree of phase .

Explanation:

Phase- The completion of a cycle ie., starting from a point O and come back again to the same point O , is known as phase . we can expess it as the complete cycle of 12 hours of a clock or a moon completes its cyle at night .

When comparing the two phases of two or more periodic motion , such as waves , the motion is said to be in phase when corresponding points reach minimum or maximum displacements simultaneously .
