1.	The string of a guitar is vibrating at a frequency of 200 hertz. Calculate its timeperiod?
Answer» Explanation:ANSWER f= 2L 1 μ T where f is frequency, T is Tension, L = length and μ is constant ∴f∝ L T ⇒ f 1 f 2 =( T 1 T 2 )( L 2 L 1 ) SQUARING on both sides and REARRANGING we GET ⇒ T 1 T 2 = (f 1 L 1 ) 2 (f 2 L 2 ) 2 L 2 =2L 1 ,f 1 =200HZ,f 2 =300Hz Substituting above values we get T 1 T 2 = 1 9
