Answer
The wavelength of a moving soccer ball is invisible using the naked eye.
Step-by-step explanation
The wavelength of a moving soccer ball is not detectable with the naked eye because it is smaller than the wavelength of visible light. The human eye is only able to see about 17 frames per second. The wavelength of a moving soccer ball can be compared to the infinite value of the de Broglie wavelength where the Plank’s constant is so small.
