will vary. This can be shown in the form of a sine wave‚ which will show the peak voltage and the zero voltage. One complete turn of the conductor is called a cycle. The number of complete cycles that occur in one second is called the frequency (Hertz). The frequency of a generator depends upon its speed For many applications including battery charging the A.C. must be converted to D.C. This is achieved when the negative half-wave is transferred to the positive and is called full-wave rectification

Standing wave Standing waves in a string — the fundamental mode and the first 6 overtones. A standing wave‚ also known as a stationary wave‚ is a wave that remains in a constant position. This phenomenon can occur because the medium is moving in the opposite direction to the wave‚ or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. In the second case‚ for waves of equal amplitude travelling in opposing directions‚ there is on

The X-linked form of the disease is caused by mutations in the COL4A5 gene encoding the alpha5-chain of type IV-collagen (Hertz‚ Juncker et al. 2001) whereas the autosomal forms are due to mutations in the COL4A3 or COL4A4 genes (Gubler‚ Knebelmann et al. 1995). The ocular manifestations of autosomal recessive Alport syndrome are probably identical to those for the X-linked

Travel and Tourism in Thailand to 2018 Published on 02nd APR. 2014 The Thai travel and tourism sector posted growth during the review period (20092013)‚ despite the global financial crisis. The growth can be attributed to the increasing number of tourists from emerging countries such as China‚ India and Russia; international tourists to the country reached 26.7 million in 2013. While forecast-period growth is expected to be undermined by political instability‚ the countrys tourism sector has

The DTMF keypad is laid out in a 4×4 matrix‚ with each row representing a low frequency‚ and each column representing a high frequency. Pressing a single key (such as ’1’ ) will send a sinusoidal tone for each of the two frequencies (697 and 1209 hertz (Hz)). The original keypads had levers inside‚ so each button activated two contacts. The multiple tones are the reason for calling the system multifrequency. These tones are then decoded by the switching center to determine which key was pressed.

The frequency is the number of waves that pass through a particular point in 1 second. Frequency is measured in hertz (Hz). Last by not least‚ amplitude is the vertical distance from the midline of a wave to the peak. X-rays are very fast moving‚ small energetic particles.
