Vibrations and Waves: Energy and Motion

1. Vibrations and Waves: Energy and Motion

What is a wave? What causes waves, and how do they travel from one place to another? This lesson will guide you through the basics of waves. We'll discuss their origins from vibrations and investigate how they carry energy through a medium.

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

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

How do we measure and describe waves? How do waves differ based upon their shapes? This lesson will guide you through the five wave parameters - period, frequency, amplitude, wavelength, and speed - that we use to characterize waves.

Transverse & Longitudinal Waves: Definition & Examples

3. Transverse & Longitudinal Waves: Definition & Examples

What comes to mind when you think of a wave? Chances are your mental image takes the form of a transverse wave. But, longitudinal waves are just as important, and understanding the difference is vital to learning about waves. In this lesson, explore both types of waves and the unique characteristics of each.

Diffraction: Relation to Sound & Light and Effects of Wavelength

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

This lesson explores diffraction as one of the many behaviors of waves. Learn how diffraction occurs in sound and light waves and how it is affected by the wavelength of a wave. Find out how animals use diffraction to communicate and how scientists use it to study molecules.

Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

5. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.

Reflection: Angle of Incidence and Curved Surfaces

6. Reflection: Angle of Incidence and Curved Surfaces

How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.

Constructive and Destructive Interference

7. Constructive and Destructive Interference

What happens when one wave meets another? Do the waves converge to make one giant wave? Or, do they destroy each other? In this lesson, we'll explore the workings of wave interference.
