The neutron interference pattern of the figure was made by shooting neutrons wit

Question

The neutron interference pattern of the figure was made by shooting neutrons with a speed of 300 m/s through two slits spaced0.10 mm apart.
Part A
What was the energy, in eV, of the neutrons?
Express your answer using two significant figures.
in eV


Part B
What was the de Broglie wavelength of the neutrons?
Express your answer using two significant figures.
in nm


Part C
The pattern was recorded by using a neutron detector to measure the neutron intensity at different positions.Notice the 100 micrometer scale of the figure. By making appropriate measurements directly on the figure, determine how far the detector was behind the slits
in m

Please show work and I need the correct answer also
I will rate 5 stars if it all works out thanks you

Explanation / Answer

0.5*m*v^2 =45000*1.67*10^-27kg =7.515*10^-23kg lemda=h/p =1.32 nm
