KIRAN DEVI answered • 42 minutes agoWhen a transmission line is terminated by an impedance Z, then reflection coefficient are:
Here, Z0 = Characteristic impedance of transmission line.
Since Z = Z0 therefore reflection co-efficient of voltage (pv) and current (pI) both will be zero, i.e there will be no reflection of incident wave.

These oscillator use transistors for converting dc voltage into sinusoidal ac voltage. Since transistor is used in active region, therefore there is substantial loss of power which decreases efficiency. In high power applications inverters are used instead of transistors and the inverters operate in saturation region or cut-off region. Thus, assertion is true but reason is false.
