What is the approximate wave length of an X Band Radar operating on a frequency of approximately 9500 MHz?
AI Explanation
The correct answer is A) 3 cm.
The wavelength of an electromagnetic wave is inversely proportional to its frequency, according to the formula: wavelength = speed of light / frequency. Given that the X Band Radar operates at a frequency of approximately 9500 MHz, the wavelength can be calculated as 3 cm.
The other options are incorrect because they do not match the calculated wavelength. Specifically, 10 cm, 30 cm, and 100 cm would correspond to lower frequencies that are not in the X Band range.
