Question

Is it possible to create an experimental setup in which there is only destructive interference?

a. Yes, by adjusting the slit width and distance between slits appropriately.
b. No, destructive interference always coexists with constructive interference.
c. Yes, by using a single slit instead of a double slit.
d. No, destructive interference is a theoretical concept and cannot be experimentally realized.

Answer 1

Yes, it is possible to create an experimental setup in which there is only destructive interference by adjusting the slit width and distance between slits appropriately in a double slit setup.

Step-by-step explanation:

Yes, it is possible to create an experimental setup in which there is only destructive interference. Destructive interference occurs when the path length difference between two waves is an odd multiple of half the wavelength. This can be achieved by adjusting the slit width and distance between the slits appropriately in a double slit setup. By making the distance between the slits equal to an odd multiple of half the wavelength, the waves arriving at different slits will be out of phase and cause destructive interference. Thus, option a. Yes, by adjusting the slit width and distance between slits appropriately is the correct answer.
