What you’ll learn6 learning objectivesChoose one objective for a focused lesson, or study the complete topic.—C.4.1—Standing wave formation• Standing waves form by superposition of identical opposite-travelling waves.Syllabus objective—C.4.2—Nodes and antinodes• Identify nodes, antinodes, amplitude and phase along standing waves.• Include relative amplitude and phase difference along the standing wave.Syllabus objective—C.4.3—Strings and pipes• Know standing-wave patterns in strings and pipes.Syllabus objective—C.4.4—Resonance• Resonance relates driving frequency, natural frequency and amplitude.Syllabus objective—C.4.5—Damping and resonance• Damping reduces maximum amplitude and shifts resonant frequency.Syllabus objective—C.4.6—Types of damping• Compare light, critical and heavy damping effects.Syllabus objective
