Hello aspirant,

Hope you are doing well

It is quite difficult to make diagram here. I'll try my best to explain this without diagram

Matter Waves :- In Universe a wave to be associated with each moving material particle which is called matter wave. It is also known as De-Broglie waves.

Properties:-

• These waves neither electo-magnetic wave nor mechanical wave
• The speed  of matter wave is greater than speed of light
• The Wavelength of matter wave is order of 10 power -30 m (minimum) and maximum 1.67 * 10 power -10 m
• The wavelength of matter wave is inversely proportional to the velocity and mass of particle.

In phase:- If both signal are at the highest peak with same time is known as in phase.

Out of Phase:- If one signal is at highest peak while other it is at lowest peak Then it is known as out of phase.

I hope this will help you.

Fell free to ask any query.

All the best.
