Correct Option
Statement 1 is incorrect. A geostationary satellite orbits at an approximate altitude of 35,786 km (or 36,000 km) above the Earth's equator. At this specific height, its orbital period matches the Earth's rotational period of 24 hours, making it appear stationary relative to a fixed point on the Earth's surface. The stated height of 10,000 km is significantly lower than the geostationary orbit required for such an orbit.
Statement 2 is correct. Frequency Modulation (FM) transmission is known for its high-quality audio output. This is primarily because FM signals encode information in frequency variations, making them inherently less susceptible to noise and interference. Most atmospheric and man-made noise primarily manifests as amplitude variations. FM receivers are equipped with limiters that effectively remove these amplitude variations from the received signal, thus significantly improving the signal-to-noise ratio. While the statement mentions "frequency variations" as the general nature of noise, the core principle is FM's robustness against various forms of interference, particularly amplitude noise, leading to superior sound clarity compared to Amplitude Modulation (AM).
Incorrect Options
Option (a) is incorrect because Statement 1 is false.
Option (c) is incorrect because Statement 1 is false.
Option (d) is incorrect because Statement 2 is correct.
