Golf ball

Abstract

A golf ball includes a core and a cover. A difference (FB2−FC2) between a secondary natural frequency FB2 of the golf ball and a secondary natural frequency FC2 of the core is not less than 80 Hz and not greater than 420 Hz. The golf ball having a sum (FB2+FC2) of not less than 4000 Hz is preferable. Preferably, the FC2 is not less than 1800 Hz and not greater than 2500 Hz. Preferably, the FB2 is not less than 2000 Hz and not greater than 2800 Hz. Preferably, an amount of compressive deformation Dc is 2.30 mm to 3.90 mm. Preferably, an amount of compressive deformation Db is 1.80 mm to 3.30 mm. Preferably, a thickness Tc is 0.80 mm to 2.10 mm. Preferably, a Shore D hardness Hc is not less than 52 and not greater than 65.
