STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY If transverse waves of constant

SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

Tsakas Spyridon GLOBALIZATION AND INEQUALITY It seems like every day in the news and newspapers there is yet another mention of globalization and whether or not it is good or bad. Does anyone really know what the term actually means or stands for though? There are many varying definitions of this term however the most appropriate since it is proposed by the World Bank would have to be the one cited by Branko Milanovic which states that it is the “freedom and ability of individuals

what is a wave? a wave is a disturbance which travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself. if a stone is dropped in a pond or swimming pool‚ ripples or waves are seen spreading on the surface of the water from the point where it was dropped. the water itself does not move in the direction of the ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical
