Hello,(adsbygoogle = window.adsbygoogle || []).push({});

Thank you all that helped me on the last problem. This other problem is also giving me a little problem.

Two sunusoidal waves travel in oppoiste directions interefere to produce a standing wave with the wave function.

y=(1.50 m) sin(.400x) cos(200t)

where x is in meters and t is in seconds. Determine the wavelength, frequency, and speed of the interfering waves.

Ok this is what I got...

Wavelength is =(velocity/frequency)

Frequnecy is = 1/time

now the problem i ran into is this is a simple plug in and find result problem however from the standing wave funtion what numbers go where. I cant seem to find it. Any help will be greatly appreciated.

Thank You

Jenn
