Question

The formation of interference patterns by electrons is best explained using which concept?

Answer 1

The correct option is D.
Interference pattern refers to a series of alternating dark and bright bands of lights, which are produced as the result of light interference. The interference pattern has to do with light waves and it has characteristic nodal and anti-nodal lines, thus its concept can be best explained using the concept of matter as a wave.

Answer 2

Answer:

D. Matter as a wave

Explanation:

electron is taken as particle because it is considered with small mass and charge. While electron in motion it also exhibit many properties similar to particles.

Like we can write the momentum associated with an electron given by

$P = mv$

so in that all explanation if we have to find the interference due to electrons then we can say by De Broglie hypothesis that wavelength associated with moving electrons is given as

$\lambda = \frac{h}{mv}$

now as per this theory electron also shows the property of interference and diffraction.

so here we will have correct answer as

D. Matter as a wave
