Time period of a wave in a medium is the time taken by:a)a compression...
Explanation:
A wave is a disturbance that travels through a medium from one location to another with the transfer of energy but not the transfer of matter. The time period of a wave in a medium is the time taken by an oscillation to pass through a point.
What is Time Period?
The time period is the time taken by one complete cycle of oscillation of a wave. It is denoted by T and is expressed in seconds (s).
How is Time Period Related to Frequency?
The time period and frequency of a wave are inversely proportional to each other. The frequency is the number of oscillations per second and is denoted by f. It is measured in Hertz (Hz). The relation between time period and frequency is given by:
f = 1/T or T = 1/f
What is Meant by Compression and Rarefaction?
In a longitudinal wave, the wave travels in the same direction as the oscillation. The region where the particles are compressed is called a compression and the region where the particles are rarefied is called a rarefaction.
Why is Option C Correct?
The time taken for a compression or a rarefaction to pass through a point is not the time period of the wave. It is the time taken for one complete cycle of oscillation to pass through a point. Therefore, option C is correct as the time period of a wave in a medium is the time taken by an oscillation to pass through a point.
Conclusion:
In conclusion, the time period of a wave in a medium is the time taken by an oscillation to pass through a point. It is related to the frequency of the wave and is inversely proportional to it. The understanding of compression, rarefaction, and longitudinal waves is also important in understanding the concept of time period.
