# calculate the velocity of a neutron with a wavelength of 75 pm

I used 1. to calculate the energy which was 1.51 x10-10 J. Then i subbed the energy into 2. and got a velocity of 4.24 x108 m/s. LOL obviously im going wrong some where how can a neutron be going faster than light! Q12 :Calculate the (a) momentum, and (b) de Broglie wavelength of the electrons accelerated through a potential(1) De Broglie wavelength () and velocity (v) are related as: h/mnvAnswer : Wavelength of a proton or a neutron, 10-15m Rest mass energy of an electron: m0c2 0.511 Compare its de Broglie wavelength to that of an electron moving with a velocity of 5 10 6 m/s.2 pm 73.2 pm in a Beryllium.CH 02 WAVE NATURE OF MATTER 61 2-2 TESTING DE BROGLIES HYPOTHESIS Problem 2-37 A neutron crystal spectrometer utilizes crystal planes of spacing d Calculate the wavelength of a neutron that has a velocity of 250 cm/s.D) 160 nm. Using the de Broglie analogy h/mv (particles with mass m, moving with velocity v behave in some ways like waves). Compare the properties of electron, proton, and neutron. (b) Rutherfords atomic model is based on the scattering of a-particles from a thin gold foil.(b) Convert the mass of electron into grams and velocity of light into cms-1 , and then calculate the wavelength of an electron in cm. In 1999, a research team in Vienna demonstrated diffraction for molecules as large as fullerenes.[14] The researchers calculated a De Broglie wavelength of the most probable C60 velocity as 2.5 pm. When the neutron wavelength is determined by time-of-flight, T/Tp different wavelength slices can be used simultaneously. Let us calculate the scattering length density for quartz SiO2 Density is 2.66 gm.cm-3 Molecular weight isPlugging in the numbers -- 864 or a neutron velocity of. What wavelength of radiation must be used to eject electrons with a velocity of 2.52x106 km/s?You never can calculate the wavelength for radiation(photon) by de-Broglie equation.

Calculate the frequency of hard X-rays with a wavelength of 55 pm.6. When light with a wavelength of 86.0 nm is incident upon a metal surface, electrons are ejected with a velocity of 4.25 x 105 m/s. Calculate the de Broglie wavelength of a neutron moving at 1.00 of the speed of light.
