Document Summary
The general part of 1. 8 was extremely dense and hard to follow. Unless i misunderstood the question, here"s my take on this: the speed of a wave is not simply defined by. , where t is the tension on the string. T /(cid:541) and mu is the mass (of the string) per unit length. , it can be altered by (cid:540) * f. If there is a path difference equal to lambda/2, there will be destructive interference, and such a path length difference of lambda/2 will lead to a phase difference of pi. Increasing the intensity of the light will in turn increase the number of electrons released when the light hits the metal, and thus increases current (since more electrons are going across and completing the circuit) A complex number, since the probability is defined by z*z where z = x + i y and z* = x i y.
