Alternate current

Hello!
I need solve 2 questions, I tried but im so bad at physics :(

1. If the frequency in the network is 50Hz, what is the period of this voltage?
2. The effective voltage value in the network is 230V. What is its maximum value?

I would like an explanation with a calculation for my understanding!!

Thanks in advance you all!
