Question

based on what we know about speed and impedance of waves explain how changing the mass and the tension (both mass and tension) of a material increases or decreases its IMPEDANCE. dont reverse the relationship between speed and IMPEDANCE. please explain in detail. thank you

Answer 1

Solution:-

Let Impedence is Z and speed is v.

T is tension and m is mass of string .

  

so if tension increases impedence increases.

where k is spring constant.

so if mass increases impedence also increases but compare to tension less.

I hope you inderstand.

Thanks!
