Wave Optics Set 2

A point source of electromagnetic radiation has an average power output of . The maximum value of electric field at a distance from the source is

In an electromagnetic wave, the amplitude of electric field is , the frequency of wave is . The wave is propagating along -axis. The average energy density of electric field, in , will be

A beam of light of wavelength 600 nm from a distant source falls on a single slit 1 mm wide and the resulting diffraction pattern is observed on a screen 2 m away. The distance between the first dark fringes on either side of the central bright fringe is

Two light sources are said to be coherent if they are obtained from

When the angle of incidence on a material is , the reflected light is completely polarized. The velocity of the refracted ray inside the material is

In Fresnel's biprism experiment the distance between source and biprism is and that between biprism and screen is and angle of prism is . The fringe width with light of wavelength will be

If white light is used in the Newton's rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light is complementary to that observed in the transmitted light through the same point. This is due to

In young's double slit experiment distance between slits, =distance of screen from the slits). At a point on the screen resultant intensity is equal to the intensity due to the individual slit . Then the distance of point from the central maximum is

The wavelength of the matter waves is independent of

The graph showing the dependence of intensity of transmitted light on the angle between polarizer and analyser, is
