Assume you have a laser based michelson interferometer. what happens to the interference pattern if you turn the beam splitter just a bit (a few mrad)? the interferometer was perfectly aligned from the beginning calculate the distance between the fringes in case we use a laser of ? -0.61nm and ? -5 mrad?

Which of the following is an example of motion in two dimensions?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
