The undergraduate curriculum for physics and electrical engineering have some similarities that students may not be aware of. With both majors you get to see circuits, basics physics concepts, and even...

Optical physics. Explaining and what Refraction, total internal reflection and dispersion is. Refraction is the bending of the light rays path, when it passes a new medium. When the index of refraction is greater in the new medium and...

This is a lecture video explaining the concepts of specular and diffuse reflection. The video discusses how light rays follow the law of reflection, where the angle of incidence is always equal to the angle of reflection. It gives...

In this video, I break down Rotational Kinematics, the first part of Unit 5 for AP Physics 1. From angular displacement to centripetal acceleration, we cover key concepts crucial for mastering rotational motion. You'll learn about key...

The video demonstrates how to investigate the refractive index of a material by measuring the angle of incidence and refraction of light as it passes through a block of glass. The narrator explains the concept of refraction and shows how...

This video is a tutorial on how to conduct an experiment investigating the reflection and refraction of light using a glass block. The video goes over the steps required to set up the experiment and make measurements of the angle of...

How does physics define power? How would you write the concept of power? In some situations, why use horsepower instead of watt?<br/>
Physics Power, Part 1

When we look at distant stars, we are looking back in time. What is a light year, how is it measured and why do we measure distance in terms of time?

In this video, we explore the concept of how telescopes allow us to see objects that are light years away, giving us a glimpse into the past. By understanding how light reflects off objects and travels to our eyes, we can comprehend how...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

What do we think the universe is quantum? What if the universe was not quantized?

Classical mechanics was doing just fine after Isaac Newton reduced nearly all mechanical phenomena to a single powerful equation:...

Researchers all over the world use a technology called optogenetics that allows them to turn neurons on and off in living laboratory organisms by exposing them to certain types of light. Stephen Boppart of the University of Illinois at...

Spacetime, as a concept, is related to a space that consists of 4 dimensions instead of the regular 3-dimensional space. As early as 1905, Einstein proposed a now widely popular theory that the speed of light is independent of the motion...
