how does the wave pattern of a loud note differ from a soft note? represent it through a graph
Answers
Answer:
Hint : Here, we are given the loud note and the soft note and have to define the difference between them. Loudness is defined as the greater the amplitude is the greater will be the loudness. Small amplitude means small will be the loudness. Draw a suitable diagram and show the difference.
Complete Step By Step Answer:
As we have been told, there are loud notes and soft notes. We have a specific diagram to explain the difference between the two notes as shown in the figure.
In the above diagram, we can see that amplitudes have the difference i.e. A1>A2
The loudness of the wave is directly proportional to the square of the amplitude. The greater is the amplitude the greater will be the loudness.
Let us now take a look at the above diagram, in the above diagram we can see that in diagram (1) amplitude is larger than that of the amplitude of the (2). Thus, we can say that diagram (1) is the wave of loud note and diagram (2) is the wave of soft note. The soft note has a lesser amplitude than that of a loud note.
In this way, the wave patterns differ from each other by amplitude. The larger the amplitude is, the greater will be the loudness and for softness, less amplitude is required.
Note :
We have discussed the nature of loudness and know that the loudness of the wave depends on the size of the amplitude and the loudness is directly proportional to the square of the amplitude i.e. LαA2 study the amplitudes of the wave patterns given if the difference is asked in terms of loudness, then you must look for the measure of amplitudes of the waves to be compared.
