Vibrations and Waves: Energy and Motion

1. Vibrations and Waves: Energy and Motion

When an object is manifesting a repetitive motion over the same path in a rhythmic way, it is vibrating, which means waves are being formed. Learn about vibrations and waves, amplitude and energy.

Transverse & Longitudinal Waves: Definition & Examples

2. Transverse & Longitudinal Waves: Definition & Examples

In transverse waves, particles of a medium move perpendicular to the wave's direction of travel and in longitudinal waves, the particles move parallel. Explore the definition and examples of these waves, how they travel through solids, liquids, and gasses, and learn about seismic waves.

Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

3. Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

Wave parameters refer to the different ways waves are measured. Examine how waves are characterized by wavelength, amplitude, period, frequency, and/or speed.

Diffraction: Relation to Sound & Light and Effects of Wavelength

4. Diffraction: Relation to Sound & Light and Effects of Wavelength

Diffraction describes a unique behavior of waves where they bend as they travel through certain mediums. Explore the diffraction of sound and light, and the effects of wavelength on diffraction.

Constructive and Destructive Interference

5. Constructive and Destructive Interference

When two waves meet while traveling in the same medium, they disrupt each other in a process called interference, which produces an entirely new wave. Discover the two types of interference, constructive and destructive, and learn how a single wave can interfere with itself.

Resonance: Definition & Transmission of Waves

6. Resonance: Definition & Transmission of Waves

Resonance is when the amplitude of an object's oscillations is increased by the matching vibrations of another object. Explore the definition, transmission of waves, resonate frequency, and resonance in music.
