Do the properties of the waves (wavelength,frequency) emitted by a particle or object depend upon the velocity, or as to say its kinetic energy? Is the De Broglie equation $E = h \nu $ applicable to matter waves as well?
These are two different questions.
Does the properties of the waves(wavelenth,frequency) emitted by a particle or an object depend upon the velocity
Yes, according to relativity, the emission lines of atoms depend on their velocity; it is the relativistic Doppler effect Here the wavelength is the wavelength of the electromagnetic wave emitted by an electron falling on a lower-energy orbital, for example.
is the de-broglie equation E = h(v) applicable to matter waves
The relation is $E=h\nu$ and also applies to the matter waves, that are described by Schroedinger equation. But the corresponding $\nu$ has little to do with the wavelength of an emitted radiation.
1- Matter wave is not emitted by the particle, but it is a probability density wave-function. If you calculated the amplitude of this function, squared it, and integrated the result over a certain volume, it will give you the probability to find the particle within this volume
2- Yes, Total Energy (rest energy + kinetic energy)= $hf$, where $\lambda f = u $, and $u$ is the speed of the matter wave $u$ is higher than light speed as it is the speed on a mathematical function, not a physical object, energy or information.
The relation between $u$ and $v$ is:
$C^2= uv$, where $v$, is the particle speed, and C is the speed of light in free space.
