k
What is the variable for the angular frequency?
omega (w)
What is the variable for a phase?
psi
What is the equation for an angular wave number?
k = 2pi/lambda
What is the equation for angular frequency?
omega (w) = 2pi(frequency)
What is the variable for wavelength?
lambda
What is the variable for frequency?

What is the equation to find the maximum transverse speed of a point on the cord?
V_m = (absolute value [omega(w)]) (y_m)
What is the equation to find the speed of the wave?
V = (lambda)(frequency)
What are the nodes, antinodes, and lambda of a closed pipe?
lambda = 4L, n=a=1
lambda = 4L/3, n=a=3
lambda = 4L/5, n=a=5
What are the nodes, antinodes, and lambda of an open pipe?
lambda = 2L, n=1, a=2
lambda = L, n=2, a=3
lambda = 2L/3, n=3, a=4
Describe the concept of wave interference. Discuss the concept of fully constructive and destructive waves.
Wave interference is the process of two waves coming together while traveling. Fully constructive is adding the two waves together to form a larger wave. Fully destructive is adding two waves to create a smaller or no wave.
V_n/V_0
sqrt{tau/mu} = sqrt{N}
What are the three basic heat transfer mechanisms, and a small description?
conduction - metal spoon in gumbo
convection - furnace
radiation - heat from solar rays
