what happen to the wavelength if tension increased?

Answer 1

If the tension in a wave-producing medium is increased, the wavelength of the wave will decrease. This relationship is described by the principle known as the wave equation, which states that the velocity of a wave is equal to the product of its wavelength and frequency. As the tension increases, the wave speed also increases, but since the frequency remains constant, the wavelength must decrease in order to maintain this relationship.
