T = 2π√(L/g)whereT is the period in seconds (s)π is the Greek letter pi and is approximately 3.14√ is the square root of what is included in the parenthesesL is the length of the rod or wire in meters or feetg is the acceleration due to gravity (9.8 m/s2 or 32 ft/s2 on Earth)L = gT2/4n2L = 9.8 m/s2 * (1.20 s)2 ÷ 4(3.14)2L = 9.8 m/s2 * 1.44 s2 ÷ 4(9.86)L = 14.11 m ÷ 39.44 L = 0.36 mThe length of the rod is 0.36 metres
