A particle with rest mass `m_0` is moving with velocity c. what is the de-Broglie wavelength associated with it?

The de Brogile wave corresponding to a particle of mass .m. and velocity .v. has a wavelength associated with it.

A particles A with mass m_A is moving with velocity v and hits a particle B (mass m_B) at rest (one dimensional motion) find change in the de-Broglie wavelength of the particle A. Treat the collision as elastic.

A electron is accelerated through a potential difference of 100V. What is de-Broglie wavelength associated with it? To which part of the electromagnetic spectrum does this value of wavelength correspond?

Show that circumference of the Bohr orbit for the hydrogen atom is an integral multiple of the de-Broglie wavelength associated with the electron revolving around the orbit.

A particle is moving with a speed three times as that of an electron.If the ratio of de-Broglie wavelength of the wave associated with the particle to that with the electron is 1.813 xx 10^(-4) ,find the mass of hte particle.Can you identiify hte particle?Give that mass of the electron = 9.1 xx 01^(-31) kg.

Mention the significance of Davisson and Germer's experiment. An alpha-particl e and a proton are accelerated from rest through the same potential difference V. find the ratio of de-Broglie wavelength associated with them.
