Recommendation It is a pleasure to write a letter of recommendation for Mr. Rutwik Reddy Reddy‚ a deserving student‚ for admission to pursue Master’s Degree at your University. I have taught him the courses of “Electromagnetic waves and Transmission lines” and “Optical Communications” .This interaction with him provides me sufficient information to gauge and asses the intellectual capability and analytical skills that he has developed during his course.

(13 points) A Doppler radar is an important tool used to measure the velocity and direction of a moving object. The Radar actually has transmitters that produce and release electromagnetic waves in the form of microwaves or radio waves. These waves are sent out and when they reach something they reflect or

The star is moving away from us‚ as the wavelength is in the redder area of the electromagnetic spectrum. 21. The method of identifying elements by their spectral line patterns is similar to identifying people by their fingerprints since both of them are characteristics that are unique to an individual. It is almost impossible to find

Radiation Protection & Radiobiology Notes Human Biology Human Response To Ionizing Radiation Early Effects of Radiation: When response occurs within minutes or days after exposure. Late Effects of Radiation: When response is not observed for many months or years after exposure. Effects of fetal irradiation: Death‚ malformation‚ malignancy‚ diminished growth. Composition of Human Body Cell Theory: 85% of the body is hydrogen and oxygen. Hydrogen: 60% Oxygen: 25.7% Carbon: 10.7% Nitrogen:

After the message is boosted at a cell tower‚ state two different ways the message may be sent to the receiving mobile phone. If you are far away from the person the electromagnetic or microwaves are converted in to light energy transmitted through optic fiber cables in the land base telephone systems‚ the signal is boosted and sent to another cell tower closest to the receiving mobile phone. That tower then sends the signal

and caused the compass to not point in the direction of the current. He later proved this through an experiment which became a huge breakthrough in this time period. In future experiments Michael Faraday proposed that light is really just an electromagnetic wave‚ but it took almost 15 years for him to convince the skeptics that this is really true. This was due to the help of Professor James Clerk Maxwell who through the use of his mathematical skill was able to back up Faraday’s proposal. James
