Final answer:
The name of the uniformity test performed with a collimator in physics is called the Collimator Uniformity Test.
Step-by-step explanation:
The name of the uniformity test performed with a collimator in physics is called the Collimator Uniformity Test. A collimator is used to create a well-defined, narrow beam of particles or radiation by restricting the direction of particles or radiation allowed to pass through it. In the Collimator Uniformity Test, the collimator is used to ensure that the radiation beam is evenly distributed and uniform. This test is important in various applications, such as in medical imaging to ensure accurate and consistent results.
