QUANTUM PHYSICS You have accidentally been beamed into an alternative universe, where first graders love broccoli, where high schoolers do all their homework right after school every day, where UCF students actually CAN finish, but in which, sadly, Justin Bieber is still a dweeb. In this mysterious alternate universe, quantum physics still holds but Planck's constant is different h = 3.6 kg m² S much larger than in our home universe. Calculate the wavelength of a neutron in this alternate universe when the momentum of the neutron is Pn = 1.44 x 10-5 kg m S Type in the numeric part of your answer to the nearest kilometer. E.g., if your wavelength is d=560850 m, then type in 561.

Answer 1

Soin using the de broglie wavelength equation x = h since here h mu P h = 3.6kg m² S Pn- 1.44x10-5 - 5 kg my ... = 3.6 (neutron momentum) 1.44X100 -5 - 306 X 105 m 1.44 )) 2.5 X 105 m 1250 km Ans,
