The correct Answer is:
To solve the question regarding the significance of the length of the antenna in communication systems, we can analyze each option provided: ### Step-by-Step Solution: 1. **Understanding Antenna Length**: - The length of an antenna is typically related to the wavelength of the electromagnetic waves it is designed to transmit or receive. The standard length of a half-wave dipole antenna is approximately half the wavelength of the frequency it operates at. 2. **Analyzing Option A**: - The statement "The length of the antenna limits the frequency of EM waves to be radiated" is true. The antenna must be of a certain length to effectively transmit or receive specific frequencies. If the antenna length is not appropriate for the wavelength of the signal, it will not radiate efficiently. 3. **Analyzing Option B**: - The statement "makes the users to opt for higher frequency transmission" is also true. Higher frequency signals require shorter antenna lengths. Therefore, if users want to transmit at higher frequencies, they will need to use antennas that are appropriately sized for those frequencies. 4. **Analyzing Option C**: - The statement "is insignificant during transmission" is false. The length of the antenna is significant during transmission because it affects the efficiency and effectiveness of the communication. A poorly sized antenna can lead to poor signal quality and transmission issues. 5. **Conclusion**: - Based on the analysis, options A and B are true, while option C is false. Therefore, the correct answer is that the length of the antenna limits the frequency of EM waves to be radiated (A is true) and makes the users opt for higher frequency transmission (B is true). C is false. ### Final Answer: - **Correct Options**: A and B are true; C is false.

Perhaps, the most commonly used mode of communication involves use of free space as a communication channel between transmitter and receiver. The various possible modes of using of free space have been described below Ground wave communication : This mode is used for low frequency as at high frequency, losses become large. This is useful for distance of the order of 1 km. Space wave communication: The signals are transmitted directly from transmitter to receiver. There is no limit to upper frequency, but its range is limited to few hundred kilometers. The range depends on the height of transmitting antenna Sky wave communication : The signals are sent towards sky They are reflected back towards earth by ionosphere. Its range can be above 500 km. But, very high frequencies (above 10 MHz) are not reflected back. Satellite communication: The signals that cannot be reflected back by ionosphere are reflected back by satellite. Moon is a passive satellite of earth. The frequency range allotted to FM radio broadcast is 88 MHz to 108 MHz. Which of the following communication channels can be used for its transmission? A. Sky wave communication only B. Space wave communication only C. Satellite communication only D. Either space wave communication or satellite communication
