If the intensity of the waves observed by two coherent sources is I. Then the intensity of resultant wave in constructive interference will be :

The light waves from two independent monochromatic light sources are given by, $y_1=2\sin (\omega t-kx) \text{and} y_2=3\cos (\omega t-kx)\text{,}$ then the following statement is correct.

Two coherent monochromatic light beams of intensities $I$ and $4I$ are superposed. The maximum and minimum possible intensities in the resulting beam are
