Water is a better medium to visualize sound waves and detect the rapid motion of a vibrating tuning fork. What happens when a tuning fork is dipped in water?īy sticking the vibrating tuning fork in a denser medium like water, the tuning fork’s energy is transferred into the act of splashing water, rather than hearing sound. When two tuning forks are sounded together produces x beats/s. What happens when two tuning forks are sounded together? These vibrations in the form of sound are transmitted through the medium near it in the form of waves. When the tuning fork is hit on a rubber pad, the prongs begin to vibrate. The tuning fork consists of a handle and two prongs (tines). What happens when you stroke the tuning fork on a rubber pad? The 256-Hz and 261-Hz forks will beat at 5 Hz. The 256-Hz and 259-Hz forks will beat at 3 Hz. What beat frequencies are possible with tuning forks of frequencies 256, 259, and 261 Hz? The 259-Hz and 261-Hz forks will beat at 2 Hz (261 minus 259). 24 Why do we use 512-Hz tuning fork? What is the formula for frequency of tuning fork?į = 1.8752 2π l2 √a2 E 12ρ where f is the frequency the fork vibrates (Hz) 1.875 is the smallest positive solution of cos x cosh x = –1 l is the length of the prongs (m) (typically 80–90 mm) E is the Young’s modulus of the material (Pa) a is the edge of the square area A of the prong cross-section (m) (typically 4– … What beat frequencies are possible with tuning forks of frequencies 256 259 and 261 Hz?
