In young's double slit experiment , the slits are 2mm apart and are illuminated by photons of two wavelength lambda_1=12000overset@A and lambda_2=10000 overset@A . At what minimum distance from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?

Electron in hydrogen atom first jumps from third excited state to second excited state and then from second excited to the first excited state. The ratio of the wavelengths lambda_1 : lambda_2 emitted in the two cases is

An electron microscope uses electrons accelerated by a voltage of 50 kV. Determine the de Broglie wavelength associated with the electrons. If other factors ( such as numerical aperture, etc. ) are taken roughly to be the same, how does the resolving power of an electron microscope compare with that of an optical microscope which uses yellow light ( lambda_(y) = 5.9 xx 10^(-7) m ) .
