Because the reflection is off of a point where the string is not allowed to move.
You can determine the phase of a reflected wave relative to the incoming wave from the freedom of motion of the point of reflection.
Since the point of reflection in the case of a string is not allowed to move, we can imagine that if it was a point on a longer string (and thus free to move) what would be the required phase of a wave coming from the distance moving in the direction of the reflected wave that does not move that point. Thus the reflected wave must always cancel the incoming wave at the point of reflection, the only phase that will fulfill this condition is the inversion (180 degree phase shift).
Because it is far too difficult to push a string.

The longest factor string is 2x2x2x3x13. It is always best to list your factor string from the least to greatest number.

Stationary transverse waves are produced on strings. This is due to the superimposition of the progressive wave and its reflection at the knife edges.
Only if the string is in a loop or there is something at the opposite ends of the string to provide a reflection or echo. If there is an echo then slightly weaker pulses will reflect off of each other near the point of origin.

Depends.... 1st string is the small, thin E string, but can also be, in some eyes, the fat E string. People always argue over this, but go with the the thin E string.
This program only suits PHP. If you want a proper one try C program for it available on web <body> <?php if(isset($_POST['submit'])) { $text = $_POST['text']; $string = mysql_real_escape_string($text); $invert = strrev($string); if($string == $invert) { echo "<br>Given number is a palindrome!!"; } else { echo "<br>Given number is not a palindrome!!"; } } ?> <form method="post"> <input type="text" name="text" id="text" /> <input type="submit" name="submit" value="Submit" id="submit" onclick="<?php $_SERVER['PHP_SELF']; ?>" /> </form> </body>
