For the half-wave rectifier, the output is present is only for one half of the input signal and clipped for the other half.
Positive half-wave rectifier clips the negative half of the input signal and only a positive part of the input signal is present. Negative half-wave rectifier clips the positive half of the input signal and only negative part of the input signal is presentIn a half-wave rectifier circuit, the average value of output voltage is:
Vavg=

Vm

π

The RMS value of the output voltage is:
Vrms=

Vm

2

Where Vm is the maximum value of supply voltage
