Explanation:

A matter wave is the inherent wave associated with all matter. They are also called De-Broglie Waves.

They are calculated by the expression

\lambda=\frac{h}{mv}λ=

mv

h

Where \lambdaλ is the wavelength.

\lambda=\frac{6.67*10^{-34}}{1.5*100}=4.417*10^{-36}mλ=

1.5∗100

6.67∗10

−34

=4.417∗10

−36

m

In phase, in context of waves, refers to waves whose troughs and crests lie on on the other. They may have different amplitudes and still be in phase.

The resultant wave is of greater amplitude than either.

Out of phase means where one wave is upwards while the other is downwards,i.e. they do not peak together but at a gap equal to half their time period, thus weakening the resultant wave.
