Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

In this video, I demonstrate a fun science trick using a simple arrow, a glass, and water. Watch how the arrow magically flips direction when seen through the glass of water—a perfect example of ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Physicists in Germany claim to have found the first naturally occurring material that has a negative, rather than a positive, refractive index. The material -- a metallic ferromagnet -- is very ...

Refraction is explained by looking into a pool and seeing Snell's law in action. Unit 6 Segment M: Refraction Refraction is explained by looking into a pool and seeing Snell's law in action. We also ...

The water bottle flipping craze, in which a partially filled bottle of water is flipped and magically lands upright, swept the globe a couple of years ago. Now a group of Dutch scientists has designed ...
