Question

To increase the frequency from 50 Hz to 200 Hz the tension in string increases to​

Answer 1

It is known that

v=Tμ−−√, where μ is the mass per unit length of the string

and the wave equation

v=fλ

Rearranging the wave equation and combining the formulae, we have

f∝T−−√

Hence, increasing T by 1.5 times results in an increase in the frequency by 1.5−−−√ times. The new frequency is thus 1006–√ Hz.

Answer 2

Answer:16 times

Explanation:velocity directly propotional to frequancy

V=f*lemda

V= under root (tension /mass per unit length)
