Similar to electron diffraction, neutron diffraction microscope is also used for the determination of the structure of molecules. If the wavelength used here is 800 pm, calculate the characteristic velocity associated with this electron.

If the velocity of the electron in Bohr's first orbit is 2.19 xx 10^6 ms^-1 , calculate the de Broglie wavelength associated with it.

Dual behaviour of matter proposed by de Brolie led to the discovery of electron microscope often used for the highly magnified images of biological molecules and other type of material. If the velocity of the electron’ in this microscope is 1.6 xx 10^6 ms^-1 , calculate de Broglie wavelength associated with the neutron.

Calculate voltage to be applied to an electron microscope, so-as to produce electrons of wavelength 0.6 overset (@)(A) . Also, calculate the speed of the electrons.

If the photon of the wavelength 150 pm strikes an atom and one of its inner bound electrons is ejected out with a velocity of 1.5 xx 10^7 ms^-1 , calculate the energy with which it is bound to the nucleus.

The molecule formula of water is H_2 O Draw electron dot and line structure of this triatomic molecule (use dots for electron of oxygen atom and cross for electrons of hydrogen atom)

In an experiment similar to Young's experiment , interference is observed using waves associated with electrons . The electrons are being produced in electron gun . In order to increase the fringe width

The electron in hydrogen atom is given by E_n = (-2.18 xx 10^-18)//n^2 J . Calculate the energy required to remove an electron completely from the n = 2 orbit. What is the longest wavelength of light in cm that can be used to cause this transition?
