Final answer:
The claim that a pointed cone produces twice as much scatter radiation is false. Scatter radiation depends on various factors, but not merely on the shape factor such as a pointed cone.
Step-by-step explanation:
The statement that a pointed cone produces twice as much scatter radiation is false. Scatter radiation occurs when X-ray photons are deflected from their original path after interacting with matter. It depends on several factors including the shape and material of the object, but not necessarily in a proportional manner as suggested by the statement. In the context of X-rays, the amount of scatter radiation can increase due to a variety of factors such as tissue density and the energy of the X-ray beam, but not merely because of a pointed cone shape only.
Regarding the reference to the number of collisions with photons and brighter light, this appears to be an incorrect explanation for the question at hand. The concept mentioned seems to relate more closely to the photoelectric effect, where an increase in the intensity of light can lead to more ejected electrons, assuming the light has a frequency above the threshold frequency of the material.
