2. A particle moving at 1000 m/s travels through an open slit, producing an interference pattern with the first minimum at an angle of 1∘ from the center. A) The particle is a helium nucleus (or 'alpha particle') with a mass of 6.7×10−27 kg. Calculate its de Broglie wavelength. B) . Determine the width of this slit. C) If the particle's speed were doubled (to 2000 m/s ), what would happen to your answer in part (B)? 3. An electron in a hydrogen atom is in the M shell (so n=3 ). A) What is the smallest orbital angular momentum this electron could have? B) What is the largest orbital angular momentum this electron could have? C) What is the maximum orbital angular momentum that could be measured in any particular direction? (This isn't a repeat of (B)) ! D) How many orbital angular momentum states could this electron have?
