Question

An experiment is conducted in which red light is diffracted through a single slit.

Part A Listed below are alterations made, one at a time, to the original experiment, and the experiment is repeated. After each alteration, the experiment is returned to its original configuration. Which of these alterations decreases the angles at which the diffraction minima appear? Select all that apply. View Available Hint(s) Select all that apply. The experiment is conducted in a water-filled tank. The distance between the slits and the screen is doubled. The slit width is halved. The slit width is doubled. A green, rather than red, light source is used. The distance between the slits and the screen is halved.

Answer 1

Solm. The diffraction angle is given by Sino: where da wavelength ala slit width. So, from above equation, following options are correct which decreases the angle of diffraction minima; (2.) The experiment is conducted in a water filled tank, ( The slit width is doubled. (e.) A green, rather than red, light source is used.
