Question

the longitudnal wave travels in a coiled spring at a rate of 4m/s . The distance between 2 compression is 20 cm. Find wavelenght and frequency

Answer 1

Hola User _______

Here is Your Answer..!!

Answer 2

Velocity=4m/a

S(distance between the 2 compression)=wavelength=20cm=0.2m

Velocity=Frequency×Wavelength

4=F×0.2

4×10÷2=F

20hz=F
