Question

Select ALL the correct definitions of the PERIOD of a standing wave.
E.g., if B and D are true and the rest are false, enter BD.

A) Twice the time for an antinode to go from y(t) = +y₀ to y(t) = −y₀.

B) The time for a complete oscillation.

C) The time it takes a point on the slinky to go from maximum displacement y(x,t) = y₁ through y(x,t) = −y₁ back to y(x,t) = y₁.

D) The time it takes an antinode to go from y(t) = +y₀ through y(t) = −y₀ back to y(t) = +y₀.

I tried CD and its not correct, only one try left.
