All the effects so far described hold true for microwave frequencies, but some are increased, and new ones are added. Atmospheric absorption and the effects of precipitation must be taken into account. So must the fact that at such short wavelengths, everything tends to happen very rapidly. Refrac..
Space Waves
Space waves travel in (more or less) straight lines. But they depend on line-of-sight conditions. So, they are limited in their propagation by the curvature of the Earth, except in very unusual circumstances. Thus, they propagate very much like electromagnetic waves in..
Importance of Radio Waves in Modern Communication
Radio waves are electromagnetic waves of wavelength 10 - 3 m and higher. Their frequency range is from a few kHz to nearly a few hundred MHz. The propagation of radio waves through the atmosphere is relevant in all modern forms of communication: radio, televi..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Incredible help, saved me from failing a test. Thank you so much. This tutoring is amazing! Explains things well, KUDOS - pam
Tutor Vista tutors are extremely helpful, patient, and nice to me. They are very talented and experienced tutors! Keep up the good work! - Loren
