You are expected to know when and how to use other equations, which are mentioned but not shown. Chapter 15 : 1) Know the relationships between wavelength ( λ ), frequency ( f ), wave velocity ( v ), angular frequency ( ω ), and wave number ( k ): v = λ f k =2 π / λ ω =2 π f v = ω / k 2) Know the formula for the wave function of a traveling wave in terms of the above quantities and the wave Amplitude, A. y ( x , t ) = A cos( kx ω t ) = A cos(2 π x / λ – 2 π ft ) and know what determines the wave direction. 3) Know the Principle of Superposition and what happens when a wave reflects off a fixed or free end. 4) Know how to determine the transverse velocity of a wave ( t t x y t x v = ) , ( ) , ( ). 5) Know the relationship between string length and wavelength for normal modes on a string.
