TED-Ed: What happens if you don't put your phone in airplane mode? | Lindsay DeMarchi
Right now, invisible signals are flying through the air all around you. Massive radio waves carry information between computers, GPS systems, cell phones, and more. And the sky is flooded with interference from routers, satellites, and,...

To Study the Universe, This Town Still Bans Cell Phones
Part of being very far away from the rest of the universe is that the signals are very faint, so sometimes you need a nice, quiet spot to listen from.

Wave Function
In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a location....

Matter as a Wave
In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

Why Is There a Magnet Inside My Dog?
Pet trackers, and lots of other electronics, have little cylinders inside them called ferrite beads. If they didn't, they'd probably be picking up the local traffic report instead.

TED-Ed: Is light a particle or a wave? - Colm Kelleher
Can we accurately describe light as exclusively a wave or just a particle? Are the two mutually exclusive? In this third part of his series on light and color, Colm Kelleher discusses wave-particle duality and its relationship to how we...

Traveling Waves
In this video Paul Andersen explains how traveling waves move through space and time. The reflection and interference of traveling waves can create standing waves which appear motionless. Examples of traveling waves in one and two...

Beats
In this video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal to the...

Wave-Particle Duality of Light
In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object a...

Light Is Waves: Crash Course Physics
The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

Wave Interference
In this video Paul Andersen explains how waves interact with objects and with other waves. When a wave hits a fixed object it will be reflected and inverted. When a wave hits a free object it will be reflected without being inverted....

Interference Patterns
In this video Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment that...
