What's the relationship between period and frequency?

They're exact reciprocals — period is how long one cycle takes, frequency is how many cycles happen per second, so T = 1/f and f = 1/T.

Does this work for sound and light waves too?

Yes, this relationship holds for any periodic wave — sound, light, radio, or mechanical oscillation — since it's a basic property of periodicity, not specific to one wave type.
