Information about Tennis Ball Clip Art Black And White
Modern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 6. 54–6. 86 cm (2. 57–2. 70 inches). Balls must have masses in the range 56. 0–59. 4 g (1. 98–2. 10 ounces). Yellow and white are the only colors approved by the ITF, and most balls produced are a fluorescent yellow known as "optic yellow", first introduced in 1972 following research demonstrating they were more visible on television.
