Q. Which of the following differences between C-band and S-band Spectrum is/are correct?

1. While S-band operates on a wavelength of 8-15 cm, C-band operates on a wavelength of 4-8 cm.
2. While S-band aren’t easily attenuated, C-band are.
3. S band radars do not require as much power as a C band radar.

Choose the correct answer using the codes given below:
Answer: Only 1 & 2
Notes: S band operates at 8-15 cm wavelength and 2-4 GHz frequency, making it suitable for long-range weather observation with large antennas. C band operates at 4-8 cm wavelength and 4-8 GHz frequency, allowing for smaller, more affordable antennas ideal for short-range weather observation. C band signals are more easily attenuated and require less power than S band.
