Q. Consider the following statements:
1.X-band radar has longer wavelength that the Doppler radar.
2.Both X-band and Doppler radars can be used to monitor weather conditions.
Which of the statement(s) given above is/are correct?
Answer: B
Notes:
Explanation –
Statement 1 is incorrect. X-band radars operate at a wavelength of 2.5-4 cm, which is shorter than the wavelengths used by other Doppler radars like S-band (8-15 cm) or C-band (4-8 cm) radars.
Statement 2 is correct. Both X-band and Doppler radars are used for weather monitoring. X-band radars are particularly useful for detecting smaller particles such as rain droplets and are often used for short-range weather observations. Doppler radars, in general, are used to measure precipitation, wind speed, and storm movement across various bands, including S-band and C-band, in addition to X-band.
