Reflection and refraction

8 videos
4D: Reflection and refraction of light rays allow us to take in the visual world around us. Perhaps you have seen surgeons outfitted with magnifying glasses in order for them to grasp the tiniest vessels of the body. And if you’ve ever looked in a mirror to comb your hair in the morning, you’ve benefited from the power of a reflective mirror. You may have also noticed that things look different when seen underwater. We will explore how light rays bend as they penetrate surfaces like water or reflect as they meet surfaces like that of a mirror.
