Question

Two small sits are cut 0.1 mm apart in a small piece of metal. Many electrons are fired at the sits with a speed of 900 m/s. A detector is placed 9 m away on the other side of the sits Part A What is the smallest distance from the central maximum that the detector will not see any electrons? 190 AED RO? Submit Request Answer If we repeat the experiment with protons instead of electrons, what is the smallest distance from the central maximum that the detector will not see any protons? Pearson

Answer 1

Solution - Griven that: mass of baseball m= 145 grams m = 0.145 kg speed of baseball v = 42 m/s Broglie wavelength of the baseball the de is given as h 1= mu Where h: Planck's constant j-s h = 6.63X1034 91 6.63 x 1034 0. 1958 42 6.63 x 1034 3 6.09 - 1x = 1.089 x 1034 m, The value of de-Broglie ware length is 1.089+1032 m. Note: Type carefully. you = 10 00 86 x 1034 m ( x my = 1.089 x 1030m (CORRECT )
