Waves & Oscillation
Two periodic waves of intensities I1 and I2 pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is
Assertion :Two thirds of possible values for phase difference result in constructive interference and one third results in destructive interference.
Reason :Interference is called constructive if the amplitude of the superposed waves exceeds that of one individual wave.
Let us list some of the factors which could possibly influence the speed of wave propagation : (i) Nature of source (ii) direction of propagation (iii) motion of source and//or observer (iv) wave length (v) intensity of the wave.
On which of these factors, if any does (a) the speed of light in vaccum (b) speed of light in a medium (say glass or water) depend ?
In double slit experiment using light of wavelength 600nm, the angular width of a fringe formed on a distant screen is 0.1∘. What is the spacing between the two slits ?
Two loudspeakers are emitting sound waves of wavelength μ with an initial phase difference of 2π. At what minimum distance from O on line AB will one hear a maxima?
There is a destructive interference between the two waves of wavelength λ coming from two different paths at a point. To get maximum sound or constructive interference at that point, the path of one wave is to be increased by
