PHY 131: University Physics II: Electricity and Magnetism

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

Join us in this enlightening video as we explore the fascinating world of projectiles and their optimal launch angles. We dive into the physics behind how a fixed initial speed affects the range of a projectile and why, for most angles, there are two choices that yield the same range. Delve into factors that affect an archer's ability to hit a target, including wind, and learn why a smaller angle, closer to the horizontal, is often preferable. Discover when and why a larger angle may be necessar

Explore the fascinating world of light coherence! In this video, we examine various pairs of light sources to determine their coherence. From candles to reflections in mirrors and soap films, we unravel the concept of coherent light sources.

Learn how to calculate total displacement when traveling west and south at different speeds and durations. Explore the direction and magnitude of your journey in this informative video.

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

Unlock the world of electrical circuits and light intensity! In this video, we explore a circuit with three lights connected in parallel, featuring an open switch. Discover what happens to the intensity of each light when the switch is closed. Join us for a journey through electrical concepts and enlightening explanations.
