Two waves from two coherent sources S and S’ superimpose at X as shown in the figure. If X is a point on the second minima and SX – S’X is 4.5 cm. Calculate the wavelength of the waves.

Light waves from two coherent sources superimpose at a point. The waves, at this point, can be expressed as `y_(1) = a sin [10^(15) pi t]` and `y_(2)a sin [10^(15) pi t + phi]`. Find the resultant amplitude if phase difference `phi` is (a) zero (b) `pi//3` (c) `pi` Also find the frequency (Hz) of resultant wave in each case.

Light waves from two coherent surface arrive at two points on a screen with path differences zero and2/2. Find the ratio of intensities at the points.

In a two-slit experiment using coherent light, the distance between the slits and the screen is 1.10 m, and the distance between the slits is 0.100 mm. The first-order bright fringe is measured to be 3.40 cm from the centerline. What is the wavelength of the light?

two waves of same frequency and intensity superimpose on each other in opposite phases after the super position. the intensity and frequency will be
