Classroom Activity for the NOVA program Volcano's Deadly Warning: In Sine Wave Science, students explore constructive and destructive interference of sine waves and plot a complex wave. Grades 9-12.

In a volcano, many such waves combine, creating complex sine waves. Wave Interference When waves overlap they interfere with each other, forming what is called an interference pattern.

While the operational differences between chorus and flanging are similar, the outputted effects of flanging can sound very ...

Sine waves are the form that sound waves take and are the "building blocks" of sound, which makes them the perfect visual expression of audio, and its periodic motion induces a trance-like effect.

For this specific waveform, we can estimate the highest sine wave frequency needed to recreate the rise time. Consider first an ideal clock signal. The spectrum of an ideal 50% duty cycle square wave, ...

In this walkthrough she demonstrates simulating a Colpitts oscillator using NI Multisim 14.3 – a deceptively simple analog circuit known for generating stable sine waves.
