Diodes has two terminals, that is switching of microwave signals and nonlinear semiconductor that is used to generate mixing or detection. While 100 years ago, the first diodes were point contact to diode used in crystal radios. Mainly, when the anode voltage is higher than the cathode voltage, the diodes will conduct. Mostly microwave industry used diodes which are made of silicon.

Understanding Point-Contact Diodes
Point-contact diodes are semiconductor devices that can detect and convert electromagnetic waves into electrical signals. They are particularly sensitive to high-frequency signals, making them suitable for specific ranges of the electromagnetic spectrum.
Detection of Electromagnetic Waves
The ability of point-contact diodes to detect various forms of electromagnetic waves varies based on their frequency and energy. Here’s a breakdown of each option:
Conclusion
The correct answer is option 'B' (Microwaves) because point-contact diodes can efficiently detect these waves due to their appropriate frequency range. This makes them valuable in applications like radar and communication systems, where microwave detection is essential.

Detection of Electromagnetic Waves
The ability of point-contact diodes to detect various forms of electromagnetic waves varies based on their frequency and energy. Here’s a breakdown of each option:
- Ultraviolet Rays: These have high energy and short wavelengths, generally falling outside the detection range of point-contact diodes. They require specialized sensors like photodiodes.
- Microwaves: These waves have longer wavelengths and lower frequencies, making them suitable for detection by point-contact diodes. Their response is efficient, allowing for effective signal conversion.
- Infra-red Waves: While point-contact diodes can sometimes detect infrared radiation, they are less effective compared to dedicated infrared sensors, which are specifically designed for that purpose.
- Radio Waves: Similar to microwaves, radio waves have longer wavelengths. However, point-contact diodes are not optimized for the lower frequencies typically associated with radio waves.
Conclusion
The correct answer is option 'B' (Microwaves) because point-contact diodes can efficiently detect these waves due to their appropriate frequency range. This makes them valuable in applications like radar and communication systems, where microwave detection is essential.
