Question

if the tension in the string is doubled and its mass per unit length is reduced to half. then the dpeed of transverse wave on it is??​

Answer 1

Answer:

speed increases 2 times

Explanation:

        V =√(F/m)

F = tension in the string

m = mass per unit length  

V directly proportional to  √F

V varies inversely to 1/√m  

As “F” is doubled and “m” is halved  

so overall 4 times the factor F/m.

but square root makes it 2 times

In this way, speed increases 2 times

Answer 2

Answer:

we know that speed of transverse waves is

v=√f/m

given tention is doubled,,,amlnd mass is half

v=√4f/m

v= 2√f/m
