LEKS Leam- Mahabuba Lovey imagine An Aternata Universe whes The Vahaey T, lOngpcom O ELECTRONIC STRUCTURE Understanding the meaning of a de Broglie wavelength Mahabub Imagine an alternate universe where the value of the Planck constant is 6.62607 x 10 15 J-s. In that universe, which of the following objects would require quantum mechanics to describe, that is, would show both particle and wave properties? Which objects would act like everyday objects, and be adequately described by classical mechanics? object quantum or classical? classical An atom with a mass of 1.0 x 1025 kg, 108. pm wide, moving at 391. m/s. quantum classical quantum classical quantum classical quantum An airplane with a mass of 1.43 x 10f kg, 15.0 m long moving at 1100. km/h.
