Wave Equation Solution: v = w/k | y(x,t) = Ae^(i(kx-wt))

Click For Summary
The discussion focuses on demonstrating that the wave equation is satisfied by the solution y(x,t) = Ae^(i(kx-wt)) when the relationship v = w/k holds true. Participants are instructed to calculate the derivatives of y(x,t) and substitute them into the wave equation to verify the solution. A participant acknowledges a misunderstanding of the problem but expresses gratitude for the clarification. The importance of correctly interpreting the relationship between velocity, angular velocity, and wave number is emphasized. Overall, the thread revolves around solving the wave equation using the specified parameters.

Homework Statement



Show that, as long as v = w/k, the wave equation is solved by

y(x,t) = Ae^(i(kx-wt))

v=velocity
w=angular velocity
k=wave number

You have just to calculate the derivatives of y(x,t) and plug them in the wave equation.
 
oh! i just read the problem wrong! sorry about that. thank you.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
