19. when the wave speed increases, will the wavelength need to increase, decrease or stay the same to get the same standing wave pattern (such as the one with 3 antinodes)?

Sagot :

When the wave speed increases the wave stay the same to get the same standing wave pattern

Standing wave are the combination of two waves moving in opposite directions . Amplitude of both the waves is same and frequency is also same . The phenomenon is the result of interference

Wavelength and frequency are inversely related to each other .

frequency = c / wavelength

so if one get  change then the other changes. As one get decrease other will increase and vise versa. . The speed of the wave depends on the medium. Change in the frequency of the wave changes its form to go into the next harmonic so the wavelength changes .Also in order to maintain the wave pattern the wavelength remain same

Hence , speed of wave will not affect the wavelength of wave.
