Harmonics and Patterns

As mentioned earlier in Lesson 4, standing wave patterns are wave patterns produced in a medium when two waves of identical frequencies…

Nodes and Anti-nodes

As mentioned earlier in Lesson 4, a standing wave pattern is an interference phenomenon. It is formed as the result of…

Formation of Standing Waves

A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves…

Standing Waves

Traveling Waves vs. Standing Waves A mechanical wave is a disturbance that is created by a vibrating object and subsequently…

The Doppler Effect

Suppose that there is a happy bug in the center of a circular water puddle. The bug is periodically shaking its legs in…

Interference of Waves

What happens when two waves meet while they travel through the same medium? What effect will the meeting of the…

Reflection, Refraction, and Diffraction

Previously in Lesson 3, the behavior of waves traveling along a rope from a more dense medium to a less dense medium (and vice…

Behavior of Waves

Boundary Behavior As a wave travels through a medium, it will often reach the end of the medium and encounter an…

As was discussed in Lesson 1, a wave is produced when a vibrating source periodically disturbs the first particle of a…

The Speed of a Wave

A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave…
