The Illustration is a schematic depiction of coherent monochromatic light incident upon a thin slit at O that diffracts to thin slits M and N where it emerges to form an Interference pattern on a screen S. Carefully count the number of wavelengths along the following paths between the double slits and the screen. & LIGHT w LA Do Number of wavelengths between siit M and point a Number of wavelengths between slit N and point a Number of wavelengths between slit M and point b Number of wavelengths between slit N and point b Number of wavelengths between slit M and point c Number of wavelengths between slit N and point c S b DARK desenesan alloans LIGHT DARK LIGHT When the number of wavelengths along each path is the same or differs by one or more whole wavelengths, is Interference constructive or destructive?, When the number of wavelengths differs by a half wavelength (or odd multiples of a half wavelength) is Interference constructive of destructive? 4 If the light used were higher in frequency, would the fringes of light and dark areas be more widely or more closely spaced? If the spacing between slits were reduced, would the fringes of light and dark areas be more widely or more closely spaced? If a greater number of equally-spaced slits, Instead of two slits, were illuminated, would an Interference pattern still be produced? (Give an example.)
