No. In order to be coherent, the light waves have to be in phase and stay in phase, and the only way for that to happen is for them to have the same wavelength and frequency.
If they are coherent, they will add, and vice versa.
Coherent
The term "mono" refers to a singular object or subject. The term "chrome" refers to colors. The term "monochrome" is a reference to a single color. ie., if two lights are monochromatic that means they have same wavelength. If two waves are monochromatic (having the same wavelength) and are of the same phase, these two waves are defined as coherent waves. Sources generating such waves are known as coherent sources.
Light waves of a single wavelength is known as being coherent. This allows constructive interference which occurs when two or more waves are in phase i.e. their crests and troughs are aligned.
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
monochromatic, coherent
If they are coherent, they will add, and vice versa.
coherent waves are waves of the same frequency (same wavelength) and constant phase difference.
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.

No, they're all waves, they're all the same!
