Homework Help: Quantum Physics energy between states

  1. Dec 17, 2005 #1
    A 1.5kg mass vibrates at an amplitude of 3cm on the end of a spring of spring constant 20N/m
    (a) If the energy of the spring is quantized, find its quantum number.
    (b) If n changes by 1, find the fractional change in energy of the spring.

    I have solved part (a) but I could not solve part (b)

    Does it mean the difference of energy between two continuous quantum?

    Yes, it asks for the difference in Energy between the 2 states. The energy difference you get should be very small, as the mass is quite large.
