For satellite telecommunication _ signals are used.
Correct answer: A. Micro waves
- A. Micro waves
- B. Ultravoilet rays
- C. Infrared waves
- D. Cosmic waves
Explanation
Option A is correct.Microwave signals are used for satellite telecommunications. This is because microwaves have a number of properties that make them ideal for this application. Microwaves have a long wavelength, which means that they can travel long distances without being attenuated by the atmosphere. This is important for satellite communications, as the satellites are often very far away from the Earth. Microwaves also have a high frequency, which means that they can carry a lot of information. This is important for satellite communications, as the satellites need to be able to transmit a lot of data

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
