In Young's double slit experiment the amplitudes of two sources are `3a` and `a` respectively. The ratio of intensities of bright and dark fringes will be

In Young's double slit experiment, the interference bright fringes are of:

In Young's double slit experiment the ratio of intensities of bright and dark fringes is 9. This means

In Young's double-slit experiment, the ratio of intensities of a bright band and a dark band is 16:1 . The ratio of amplitudes of interfering waves will be
