Hey guys i've got a few questions I didn't know how to do and would appreciate if you could help me out...(adsbygoogle = window.adsbygoogle || []).push({});

A wave generator is used to produce transverse waves in a string that is 12 metres long. Initially, the wave generator is set to a frequency of 5.0 HZ

a) How many wavelengths are being created each minute by the wave generator? (Hint: how many in one second?)

b) What is the period of the wave being gnerated?

c) If the speed of a wave in the string is known to be 15 m/s, what is the length of one wave?

d) The frequency of the wave generator is now changed so that it produces a standing wave pattern along the string. An observer counts 3 nodes along the entire length of the string. What is the frequency of the wave generator when it is producing this standing wave?

I am aware that frequency and periods are inversly related

T = Period

f = frequency

Therefore: T = 1/f & f=1/f

also:

equations we are given to use are:

v= d/t & v=f(wavelength) (velocitiy equals frequency times wavelength.)

Would love some help..

Thanks in advance.
