1) A child on a playground swing makes a complete toandfro swing each 2 seconds. The period is:
0.5 Seconds
2 Seconds
I think the answer is 2. Am I correct?
2) The period of a 440 Hertz sound wave is ___ seconds.
1/440
440
I think the answer is 440. Am I correct?

1) You are correct
2) No. 440 Hz means 440 cycles per second. Each cycle lasts 1/440 second.
