White coherent light (400 nm - 700 nm) is sent through the slits of a young's double slit experiment (figure 17-E3). The separation between the slits is 0.5 mm and the screen is 50 cm away from the slits. There is a hole in the screen at a point 1.0 mm away (aong the width of the fringes) from the central line. (a) Which wavelength (s) will be absent in the light coming from the hole? (b) Which wavelength (s) willl have a strong intensity? |
