The amplitude of two interfering waves are a and 2a respectively. The resultant amplitude in the condition of constructive interference will be:

The amplitudes of two interfering waves are 4 cm and 3 cm respectively. If the resutant amplitude is 1 am then the interference becomes

If the amplitude of two interfering light waves are not equal, then the intensity in the dark region formed in the interference pattern will be

The resultant amplitude in interference with two coherent sources depends upon :

If the ratio of the amplitudes of two interfering wave is 4:3, then the ratio of the maximumum and minimum intensities in the interference pattern is
