Diffraction Effects
In this video Paul Andersen explains how diffraction can be affected by the size of the wavelength. When waves pass through an opening or move around an obstacle a shadow region is created. The size of the shadow zone will decrease as...

Electromagnetic Radiation
In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

Specular Reflection
In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...

Wave Diffraction
In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

3 Physics Experiments that Changed the World
Physics investigates why the universe behaves the way that it does, and today, Hank tells us about the three physics experiments that he thinks were the most awesome at helping us understand how the universe works.

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...

Mechanical and Electromagnetic Waves
In this video Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.

Tal Danino: Programming bacteria to detect cancer (and maybe treat it)
Liver cancer is one of the most difficult cancers to detect, but synthetic biologist Tal Danino had a left-field thought: What if we could create a probiotic, edible bacteria that was "programmed" to find liver tumors? His insight...

Matter as a Particle
In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

Transverse and Longitudinal Waves
In this video Paul Andersen compares and contrasts transverse and longitudinal waves. Waves carry energy through oscillations. In transverse waves the oscillations are perpendicular to the direction of the wave and in longitudinal they...
