Consider interference between waves from two sources of intensities I and 4I.find intensities at pints,where phase difference is
`pi`.

Consider interfernece between two sources of intejnsities I and 4 I.Obtain intesity at a point,where the phase difference is pi//2 .

Two waves of intensities I and 4 I superimpose, then maximum and minimum intensities are:

What is the distance between the two points which have a phase difference of 2pi ?

Two sources of intensities I and 4 I are used in an interference experiment.Obtain intensities at points,where the waves from two sources superimpose with a phase different of 0

Two coherent sources of light whose intensity ratio is 64:1 produce interference fringe. Calculate the ratio of of intensity of maximum and minmum in the interfernce fring system.

One method of prodocing two in - phase point sources of light for interference is to form two images of a point source by means of the two halves of a lens,which has been split along a diameter[Fig.6.17]. How must the two halves of a 5 cm focal length lens be placed to form two real images sources0.24 cm apart and 20 cm from the source?

The difference between two acute angles of a right angle triangle (3pi)/10 rad. Find the angles in degree.

One method of prodocing two in - phase point sources of light for interference is to form two images of a point source by means of the two halves of a lens,which has been split along a diameter[Fig.6.17]. A screen placed perpendicular tot he principal axis and 80 cm from the mage sources.What is the width of central maxima formed on the screen,if the wavelength of the light used is 5.4 xx 10^(-5) cm ?
