Multiple choice questions about SHM

    1. The problem statement, all variables and given/known data
    1.Reflection goes with
    a. longitudnal wave
    b.trasnsverse wave
    c. both
    d.neither
    2.
    if mass of teh bob on a springs are increased, howe whould that affet the period of the vibrations?

    3. if a spring is released fr. progressively larger displacments, how owould this affect eh e max. velocity of teh bob.

    2. Relevant equations



    3. The attempt at a solution

    1. transverse, because reflection refers to light right?
    2. increase becase T=2pi(sq.root(m/k))
    3.increase because vmax=2pi*displacement/(T)

    For the answer to number 1) What kind of wave is light? Does light reflect? What kind of wave is sound? Ever hear an echo? (Check Wikipedia if you don't know the answers to my questions)

    Your answer to 2) and 3) are correct.

    yes it does. light is transverse and sounds is longitudinal...so i guess the answer is c. both.
