The tennis ball can then be circled around a burning light bulb in a plane(平面) __8__C__ to the floor at the same height as the bulb, keeping the axis at a(n) ___9__C_tilt toward the north. As the ball circles clo to the bulb, the dark and light sides of the ball will be clearly en, and so will the differences in light intensity on different parts of the ball.
