If Path Difference between waves is 11λ/4 then the phase difference between two waves will beCorrectIncorrect
For Minimum intensity the phase difference between two waves isCorrectIncorrect
Two waves of amplitudes A1 and A2 superimpose with each other such that A1 > A2 . The difference between maximum and minimum amplitude isCorrectIncorrect
Two coherent sources of intensity ratio α interface. In interface pattern I(max) – I(min) / I(max) + I(min) =CorrectIncorrect
The distance of a point on the screen from two slits in biprism experiment is 1.8 x 10-5 m and 1.23 x 10-5 m. If wavelength of light used is 6000 A0, the fringe width formed at that point isCorrectIncorrect
Two coherent monochromatic light beams of intensities ‘4I’ and ‘9I’ are superimposed. The maximum and minimum possible intensities in the resulting beam areCorrectIncorrect
Resolving power of telescope increases whenCorrectIncorrect
Two coherent sources P and Q produce interference at point A on screen where there is a dark band which is formed between 4th bright band and 5th dark band. Wavelength of light used is 6000 A. The apth difference between PA and QA isCorrectIncorrect
In biprism experiment the distance between source and eyepiece is 1.2m the distance between two virtual sources is 0.84 mm . Then the wavelength of light used if eyepiece is to be moved transversly through a distance of 2.799 cm to shift 30 fringes isCorrectIncorrect
Light of wavelength λ is incident on a single slit of width a and the distance between slit and screen is D. In diffraction pattern, if slit width is equal to the width of the central maximum , then D is equal toCorrectIncorrect
