The skip zone in radio wave trasmission is that range where

Options

A. there is no reception of either ground wave or sky wave
B. the reception of ground wave is maximum b ut that of sky wave is minimum
C. the reception of ground wave is minimum, but that of sky wave is maximum
D. the reception of both ground and sky wave is maximum.

Answer

### Step-by-Step Solution:

1. **Understanding Skip Zone**: The skip zone in radio wave transmission refers to a specific area where radio signals cannot be received. This area is located between the range of the ground wave and the range of the sky wave.

2. **Definition of Skip Distance**: The skip zone is sometimes referred to as the skip distance. It is the distance that a radio wave travels before it is refracted back to the ground by the ionosphere.

3. **Propagation Mechanism**: In sky wave propagation, a transmitter sends out radio waves that travel upward towards the ionosphere. Upon reaching the ionosphere, the waves are refracted back towards the Earth, creating a reception area beyond the skip zone.

4. **Characteristics of the Skip Zone**: Within the skip zone, there is no reception of either ground waves (which travel along the surface of the Earth) or sky waves (which are reflected back from the ionosphere). This means that the area between the transmitter and the point where the sky wave is received is devoid of any signal.

5. **Conclusion**: Therefore, the skip zone is defined as the range where no radio wave signals can be received, either from ground waves or sky waves.

### Final Answer:
The skip zone in radio wave transmission is that range where no signals can be received.
