Equations to memorize First exam Relation between angular frequency and frequency Relation between wave number and wavelength Relation between frequency and period Relation between wave velocity, wavelength, and frequency for periodic wave You will be given the displacement of a Simple Harmonic wave, y(x,t) = Acos[kx −ω t]. You must be able to find the velocity and acceleration of a point on the wave from the displacement equation. You will be given the displacement of a standing wave on a string, y n (x,t) = A SW sin(k n x)sin( ω n t)]. You must be able to find the velocity and acceleration of a point on the wave from the displacement equation. Wavelength and frequency of normal modes for a string tied at both ends Wavelength and frequency of normal modes for a pipe that is open at both ends Wavelength and frequency of normal modes for a pipe that is open at one end and

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
