How does interfacial energy vary with coherence?

Think of a high angle grain boundary. The structure is very disordered there and bonds have been broken. Thus, the interface is unstable and high in energy. Thus, coherence le (MORE)

What is coherent sound wave?

For two waves to be coherent both must be having the same frequency and be in phase or having constant phase difference. This is applicable for light as well as sound waves. H (MORE)

What are coherent sources and conditions for it?

Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same (MORE)

Can waves with different wavelength be coherent?

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.

What is coherent bedrock?

It is when two ig rocks form together due to a landslide that engulfes the matter and hardens over thousands of years. It is a force that is unknown to the naked by but can be (MORE)

How does positron emmission tomography work?

Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The system (MORE)
