could someone help me see how i draw the 3 graphs. I was just going to sketch a sin like graph followed by a sin graph with a phase then a 3rd graph with a larger phase.
1. Show the plot of the maxima and minima (ie:points of cons and dest. interference) for lamda= d/4, d and 2d
3. I am not quite sure what it is asking for. Do I just draw a graph that shows all 3 patterns?
Snell's Law and Light!
1. Use Snell's Law to show that a light ray which enters glass plane of wfinite width does not change direction when it exits the plate.
2. sin(theta in)/sin(theta refracted)= n2/n1
3. I know that if lamda in medium 1 does not equal lamda in medium 2, the...
[SOLVED] Violin String and Waves
1. A violin string of length 0.33m and mass 50g is under a tension of 40N. A violin player touches the string a distance L/3 from one end, which produces a node at that point. What is the lowest frequency that can now be produced on the string?
2. I have several...
1. The equation of motion is Ma(t) +rv(t) + Kx(t)=0
a) Look for a solution of this equation with x(t) proportional exp(-Ct) and find two possible values of C.

3. No clue... Please help if you can!
after thinking about it, i think its easier than i thought. we calculated w. To find the amplitude of the oscillation we take the answer in b and subtract it from a. The phase is then easy to calculate since x(o)=Asin(phi) and if x(o)=amplitude, then sin(phi)=1 and the phase is pi/2
[SOLVED] Spring Oscillation Problem!
1. A 2.0 kg mass hangs at rest from a harmonic spring with a spring constant of 500 N/m inside an elevator that is stationary.
a) by how much is the spring stretched
b) suppose that the elevator is rising with a constant upward accel of 1/3 g. By how...
ok i think i got it... the problem is basically all variables and says you drop a sphere of mass m , volume v and density p into water. The sphere drops to a distance d below the surface of the water. What it the total potential energy due to gravity and the bouyant force. It then says to assume...
I am pretty sure i know how to answer my homework problem if someone can tell me how to calculate the potential energy due to the bouyant force? I am assuming its Fr but what is r and where would you get it from?
In the problem i am given the depth from the surface at which an object is at...
1. A deep sea diver has descended a distance of 50m below the ocean surface. Asummer that he is supplied with air from the survace.
a) what is oxygen partial pressure in the lungs of the diver at this depth.
b) suppose we want the oxygen partial pressure in the lungs of the diver...
1. Some sharks have a surprising float:their livers. The shark liver contains a lot of squalene with a density of 860 kg/m^3. Estimate the weight of the liver of a 2000kg shark so it is effective as a float

1. A bubble of air of volume v forms at the bottom of a container of fluid (neglect effects of viscosity). Let H be the height of the fluid, and let ρf and ρa denote densities of fluid
and air respectively. How fast is the bubble moving when it reaches the surface?
2. What is the work performed...
1. Blood travels from a container hanging at a height H abovethe table into the vein of a persons arm. The blood pressure in the vein is 2000 Pa above 1 atm. Blood has a density of 1 g/cm^2
(a) How high should the container of plasma hang above the patient
(b)Suppose you want to drain blood...
