As much as we like to talk about vibes, actual vibrations underlie pretty much everything about the universe. From the patterns of galaxies created by the Big Bang to the existence of subatomic particles, here's how the universe runs on...

While doing some light reading of data from a telescope, Conny Aerts made a breakthrough that allowed her to lead the charge in the field of asteroseismology and win her the 2022 Kavli Prize in Astrophysics.

When physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already...

Hook up an old antenna to your TV and scan between channels. The static buzz you hear is mostly due to the ambient radio produced by our noisy pre-galactic civilization. But around one percent of that buzz is something very different –...

Learn about Horizon radiation and why it's essential for us to understand as we continue our journey towards the Unruh Effect and Hawking Radiation.

In this video Paul Andersen explains how the amplitude of a wave is a measure of the energy of the wave. He gives several examples of wave amplitude and shows you how to calculate the wave of a transverse and longitudinal wave.

We can now map the interiors of stars by "listening" to their harmonies as they vibrate with seismic waves.

Everyone loves a slow motion video of a dog shaking to dry off, but what is the science behind it?

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it's also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made....

In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini...

In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

In this video Paul Andersen details the characteristics of electromagnetic waves. Electromagnetic waves are transverse waves that can move through both mediums and vacuums. The electric and magnetic fields oscillate perpendicular to...

How DO you make a digital clock?

Master Unit 7 Oscillations for AP Physics 1 with this comprehensive review! Dive into the concepts of periodic motion and simple harmonic motion (SHM) as we explore mass-spring systems, pendulums, and energy transformations in SHM....

After a number of tutorials covering first-order differential equations, it's time to start tackling second-order differential equations. These contain a second derivative term, and they are quite useful in physics. To introduce these,...

In this video, we learn about the incredible complexity of the human brain, which consists of approximately 170 billion cells, including 86 billion neurons. These neurons communicate through synchronized impulses, creating brain waves...

Frequency is the measurement of the total number of complete cycles or oscillations that a wave goes through in one second, and it is expressed in hertz (Hz). Frequency is a fundamental attribute that dictates the rate at which a wave...

Dive into the intricate world of LC circuits with our latest video! Watch as we break down the dynamic graphs and components of inductor-capacitor circuits, exploring charge, current, and energy equations. Our animation vividly...

The SI unit of frequency, one hertz is equal to one cycle per second.
