Constructive Interference Definition:

Constructive Interference is a term used in wave dynamics which means that two waves superimpose and are in the same phase, they form a wave of larger magnitude.

Constructive Interference Explained:

To understand constructive interference we must first understand a few basic properties of a wave. These include amplitude, frequency, wavelength, and phase. If we visualize all these properties keeping in mind that an electron is also represented as a wave, the properties of all interacting electron waves will be the same.

Constructive interference is an important aspect to consider in the formation of covalent bonds, which essentially represent the overlapping of atomic orbitals (electron density).

The diagram below will help you understand these properties –
