... measured to be 4.23 m long. Suppose Jagdamba conducts experiments with her hair. First, she determines that one hair can support a mass of 25 g. She then attaches a smaller mass to the same hair and swings it in the horizontal plane. If the hair breaks when the tangential speed of the mass reaches 8 ...

L6 POLARISATION
... We have already seen that the resultant of two linear polarisations with zero phase difference is also a linear polarisation. Another special case is the combination of two elementary linearly polarised waves whose phase difference is exactly π. The resultant is a linear polarisation but its orienta ...
