Question

The wave function for waves on a string is
A)either the displacement of air molecules s,or the density $\rho$. 
B)the wave function $\varPsi$ . 
C)the electric field . 
D)the string displacement y. 
E)None of these is correct.

Quizplus · Accepted Answer

The wave function for waves on a string is the displacement of the string itself, which is represented by the variable y. Therefore, choice D is the best answer. Choices A, B, and C are incorrect as they refer to other types of waves (sound waves and electromagnetic waves) and their respective wave functions.

The Wave Function for Waves on a String Is A)either ρ\rhoρ
