Wave Optics Test - 2

Two coherent monochromatic light beams of intensities I and 4 I are superposed . The maximum and minimum possible intensities in the resulting beam are

Which of the following is conserved when light waves interfere with each other ?

In youngs double -slit experiment , an electron beam is used . If the velocity of the electrons is increased ,

In a double slit experiment instead of taking slits of equal widths , if one slit is made twice as wide as the other , then in the interference pattern

Two point white dots are 1 mm apart on a black paper . They are viewed by eye of pupil diameter 3 mm . Apporoximately , what is the maximum distance at which these dots can be resolved by the eye ? [Take waveleght of light = 500 nm]

In a YDSE bi-chromatic light of wavelegths 400 nm and 560 nm are used . The distance between the slits is 0.1 mm and the distance between the plane of the slits and the screen is 1 m . The minimum distance between two successive regions of complete darkness is

To demonstrate the phenomenon of interference , we require two sources which emit radiations

In a Youngs double sit experiment , 12 fringes are observed to be formed in a certain segment of the screen when light of wavelength 600 nm is used . If the wavelength of light is changed to 400 nm , number of fringes observed in the same segment of the screen is given by

Monochromatic blue light has been used to obtain the diffraction pattern of a narrow slit on a screen . Keeping the experimental set up unchanged if blue light is replaced by red monochromatic light , the diffraction pattern will
