Answer:
From the above, we see that for the first two types of wave, the response would be B
Step-by-step explanation:
Stationary waves occur when a traveling wave collides with an obstacle and is returned, the sum of the two waves gives a wave that does not travel over time.
There are several possibilities of standing wave; when the ends are fixed, when the ends are open, it is these two cases the relationship is
λ = 2L / n
Where λ is the wavelength, L is the length of the system and n an integer from n = 1, 2,3, ...
There is a third case in which one end is open and the other closed, in the latter case the relationship is
λ = 4L / n
Where n = 1,3, 5, ...
The wave with the smallest integer (n = 1) is the so-called fundamental wave or pattern, all other waves are called overtones.
In the first two cases the overtones are obtained from the fundamental wave plus 1
In the latter case the over tones are obtained from the fundamental wave and all the following odd numbers (2n-1)
From the above, we see that for the first two types of wave, the response would be B
For the last type of resonance there is no correct answer, since the shape of the sorbetones is 2n-1 and does not appear in your answers
