Q1. Consider the following statements:
1. A geostationary satellite is at an approximate height of 10,000 km.
2. FM transmission of music is of very good quality because the atmospheric or man made noises which are generally frequency variations can do little harm.
Which of the statements given above is/are correct?
1. A geostationary satellite is at an approximate height of 10,000 km.
2. FM transmission of music is of very good quality because the atmospheric or man made noises which are generally frequency variations can do little harm.
Which of the statements given above is/are correct?
Explanation
Statement 1 is incorrect: A geostationary satellite orbits the Earth at an altitude of approximately 35,786 km(not 10,000 km) above the equator. This altitude ensures that the satellite’s orbital period matches the Earth’s rotational period, making it appear stationary from the ground.
Statement 2 is correct: FM (Frequency Modulation) is less affected by noise because noise primarily affects amplitude, not frequency. This makes FM transmission superior in quality compared to AM (Amplitude Modulation).
