Academics

Double the slit width a and double the wavelength . B. Double the slit width a and halve the wavelength . X C. Halve the slit width a and double the wavelength . D. Halve the slit width a and halve the wavelength . In a single-slit diffraction experiment with waves of wavelength , there will be no intensity minima (that is, no dark fringes) if the slit width is small enough. Which of the following will give the greatest increase in the angular width of the central diffraction maximum? A. Double the slit width a and double the wavelength . B. Double the slit width a and halve the wavelength . X C. Halve the slit width a and double the wavelength . D. Halve the slit width a and halve the wavelength . In a single-slit diffraction experiment with waves of wavelength , there will be no intensity minima (that is, no dark fringes) if the slit width is small enough. What is the maximum slit width a for which this occurs? A. a = /2 X B. a = C. a = 2 D. The answer depends on the distance.
