Indicate the interval which represents one full wavelength.
Indicate the interval which represents one full wavelength.
The correct option is D to
Explanation of Correct option:
(d) to : We can see that this is one complete cycle. Because moving forward, the same shape gets repeated till the end of the wave.
Explanation of incorrect options:
(a) to : This is not one complete cycle, because if we go ahead from the wave particles oscillates in the negative direction, whereas from to all particle's displacement is in the positive direction. So, the shape is not repeated. So this cannot be called a wavelength.
(b) to : This is also not one complete cycle because particle displacements and shape are not get repeated by moving forward along the direction of wave propagation.
(c) to: By moving ahead from point along the direction of propagation, we see that the wave shape is not getting repeated. Because, moving ahead from , particle displacements are in negative directions whereas, after point , particles are displaced in the positive direction.
Hence the correct option is D.
