The frequency or number (f) of vibration of a string under constant tension is inversely proportional to the length (l) of the string. If a string of 48 cm
\n" ); document.write( "vibrates 192 cycles per second, find the the constant of proportionality and the number of vibrations per second a string of 32 cm will make.
\n" ); document.write( "----
\n" ); document.write( "f = k/L
\n" ); document.write( "---
\n" ); document.write( "Find \"k\" using \"a string of 48 cm
\n" ); document.write( "vibrates 192 cycles per second\".
\n" ); document.write( "---
\n" ); document.write( "192 = k/48
\n" ); document.write( "k = 9216 (constant of proportionality)
\n" ); document.write( "---
\n" ); document.write( "Equation:
\n" ); document.write( "Find \"the number of vibrations per second a string of 32 cm will make\"
\n" ); document.write( "using y = 9216/L
\n" ); document.write( "y = 9216/32 = 288 vibrations per second
