Hi, I have two question.....I spent 2 hrs on these two but couldnt fins out how to solve it...can any one show me right way? hint?(adsbygoogle = window.adsbygoogle || []).push({});

1

A sinosodial wave of frequency 500Hz has a speed of 350 m/s

a. How far apart are two points that differ in phase by Pi/3 rad?

b. What is the phase difference between two displacments at a certain point at times 1.00ms apart?

2.

the function y(x,t)= (15.0 cm) cos ((pi)x-15(pi)t) with x in meters and t in secconds, describes a wave on a taut string. what is the trasnverse speed for a point on the string at an instant when that point has the displacement y= +12.0 cm?
