bash-2.02$ man delay
No manual entry for delay

Can't answer the first part, but I imagine that hz means Hertz, properly
abbreviated as Hz. 1 Hz is 1 cycle per second or one second per cycle. 
Metric prefixes apply, therefore 1 kHz = 1000 cycles per second (0.001
seconds or 1 ms per cycle), and so on.
