What methods do physicists use to study and measure the colors of objects and materials in order to understand their physical properties and behavior, and how does this knowledge contribute to our understanding of light and optics?
What is the relationship between the colors in the electromagnetic spectrum, such as X-rays and radio waves, and the colors that we can see with our eyes, and how do these differences arise from the properties of light and optics?
What is the relationship between the laws of physics and the ability of our brains to perceive the same object as having consistent color despite changing lighting conditions, a phenomenon known as color constancy?
Can current telescopes be used to detect the presence of electric lights in cities on other planets in our solar system? Is it possible to observe the light emitted by cities on distant planets using existing technology?
