Answer 1

Concept:

Half-wave rectifiers transform AC voltage to DC voltage. A halfwave rectifier circuit uses only one diode for the transformation.
A halfwave rectifier is defined as a type of rectifier that allows only one-half cycle of an AC voltage waveform to pass while blocking the other half cycle.
A rectifier is a device that converts alternating current (AC) to direct current (DC).

The working of the same can be understood by the below diagram

The RMS value of the half-wave rectifier output is given by the expression

...........(1)

Solution:

Given to us is the value

Put the above value in equation 1
