Two source `S_(1)` and `S_(2)` of intensity `I_(1)` and `I_(2)` are placed in front of a screen [Figure a]. The pattern of intensity distribution see in the central portion is given by Figure b. In this case which of the following statement are true.

Two sources S_1 and S_2 of intensities I_1 and I_2 are placed in front of a screen. The pattern of intensity distribution seen in the central portion is given by Fig. 10.6. In this case which of the following statements are true.

Two sources S_(1) and S_(2) of intensity I_(1) and I_(2) are pIaced font of a screen [fig .6.24(a)]. The pattern of intensity distrtbution seen in the centraI portion is given in fig.6.24(b). Which of the foIIowing statements are true?

Two coherent sources of intensities I_1 and I_2 produce an interference pattern. The maximum intensity in the interference pattern will be

Two coherent sources of intensities I_1 and I_2 produce an interference pattern. The maximum intensity in the interference pattern will be

Two coherent sources of intensities I_1 and I_2 produce an interference pattern. The maximum intensity in the interference pattern will be

Two identical sources of sound S_(1) and S_(2) produce intensity I_(0) at a point P equidistant from each source . (i) Determine the intensity of each at the point P . (ii) If the power of S_(1) is reduced to 64% and phase difference between the two sources is varied continuously , then determine the maximum and minimum intensities at the point P . (iii) If the power of S_(1) is reduced by 64% , then determine the maximum and minimum intensities at the point P .

A point source of light S is placed in front of a perfectly reflecting mirror as shown in Figure. Sigma is a screen. The intensity at the center of screen is found to be I. If the mirror is removed, then the intensity at the center of screen would be
