What is the approximate wave length of an X Band Radar operating on a frequency of approximately 9500 MHz?

Correct Answer: Option A — 3 cm

X-band radar operates in the 9 GHz frequency range. Using the formula wavelength equals speed of light divided by frequency, 300,000,000 m/s divided by 9,500,000,000 Hz yields approximately 0.0315 meters, or 3 centimeters. This wavelength provides superior target resolution compared to S-band radar, as detailed in Bowditch, Volume II.
