If `lambda` is wavelength of radio signals to be transmitted, then the length of Hertz antenna is

Options

A. `lambda`
B. `lambda/4`
C. `lambda/2`
D. `2lambda`

Answer

To solve the question regarding the length of a Hertz antenna when given the wavelength (λ) of radio signals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hertz Antenna**:
- A Hertz antenna is a type of dipole antenna that is specifically designed for effective radiation of radio signals.

2. **Relationship Between Wavelength and Antenna Length**:
- The length of a Hertz antenna is related to the wavelength of the signals it transmits.

3. **Formula for Antenna Length**:
- The standard formula for the length of a Hertz antenna is given by:
\[ \text{Length of Hertz antenna} = \frac{\lambda}{2} \]
- This means that the length of the antenna is half of the wavelength of the radio signals.

4. **Conclusion**:
- Therefore, if λ is the wavelength of the radio signals to be transmitted, the length of the Hertz antenna will be:
\[ \text{Length} = \frac{\lambda}{2} \]

### Final Answer:
The length of the Hertz antenna is \(\frac{\lambda}{2}\).
