Two monochromatic sources of electomagnetic wave, P and Q emit waves of wavelength lambda = 20 m and separted by 5m as shown. A,B and C are three points where interference of these waves is observed. If phase of a wave generated by P is ahead of wave generated by Q by pi//2 then (given intensity of both waves is l ) :

One of the components of frequency of amplitude modulated wave (AM) formed by the superposition of message signal of frequency omega_1 on a carrier wave of frequency omega_2 is

The ratio of maximum intensity to minimum intensity due to interference of two light waves of amplitudes a_(1) and a_(2) is

A monochromatic light beam of wavelength 5896Å is used in double slit experiment to get interference patter on a screen. 9th bright fringe is seen at a particular position on the screen. At the same point on the screen. If 11th bright fringe is to be seen, the wave length of the light that is needed is (nearly)
