A mirror would be the best object to use from the bucket of materials to help understand how to reflect light. Mirrors are specifically designed to reflect light and provide a clear and easy-to-observe reflection, making them ideal for demonstrating the concept of light reflection. By using a mirror, one can easily see the angle of incidence and reflection, as well as how the direction of light changes upon reflection. Additionally, mirrors can help illustrate other concepts related to light, such as how the angle of reflection is equal to the angle of incidence.
