Wave Basics: Audio Guided Solution
Extra Problem 1:
A cork resting on the surface of a pond bobs up and down 3 times per second on some ripples having a wavelength of 12.7 cm. If the cork is 16.7 m from shore, how long (in seconds) does it take a ripple passing the cork to reach the shore?

Habits of an Effective Problem Solver
-
Read the problem carefully and develop a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
-
Identify the known and unknown quantities and record in an organized manner, often times they can be recorded on the diagram itself. Equate given values to the symbols used to represent the corresponding quantity (e.g., v = 12.8 m/s, λ = 4.52 m, f = ???).
-
Use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
-
Identify the appropriate formula(s) to use.
-
Perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
