Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00μm. the electrons then head toward an array of detectors a distance 1.080 m away. these detectors indicate a diffraction pattern, with a broad maximum of electron intensity (i. e., the number of electrons received in a certain area over a certain period of time) with minima of electron intensity on either side, spaced 0.514 cm from the center of the pattern. what is the wavelength λ of one of the electrons in this beam? recall that the location of the first intensity minima in a single slit diffraction pattern for light is y=lλ/a, where l is the distance to the screen (detector) and a is the width of the slit. the derivation of this formula was based entirely upon the wave nature of light, so by de broglie's hypothesis it will also apply to the case of electron waves.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
