Which of the following forms an interference pattern when directed toward two suitably-spaced slits?

a. electrons
b. sound
c. light
d. all of these
enone of these

Option d

Explanation:

Interference is the phenomenon in which two or more waves having the same frequency combines or cancel out each other to form a resulting wave with the amplitude equals the sum of the amplitudes of the waves that are combined.

Thus it is clear that the particle with the wave nature can produce interference pattern. Hence, electron, light, sound, all of these produces interference pattern when directed towards the slits that are suitably spaced.
