Question

1. When are standing waves produced?

2. What does an object's resonant frequency depend upon?
3. What has to happen in order for resonance to occur?
4. How do incident and reflected waves differ?
5.Expain the nodes and anti-nodes on standing waves.

Answer 1

1.) Standing waves are produced when two waves with the same frequency and amplitude traveling in opposite directions interfere with each other.

2.) An object's resonant frequency depends upon its physical properties, such as its size, shape, and composition.

3.) For resonance to occur, the frequency of an external wave must match the natural frequency of the object, causing the amplitude of the vibration to increase.

4.) Incident waves are the waves that are initially produced and travel towards the boundary or interface between two mediums, while reflected waves are the waves that bounce back from the boundary or interface after encountering it.

5.) Nodes and anti-nodes are points on a standing wave where the amplitude of the wave is always zero and maximum, respectively. Nodes occur at points where the wave's displacement is at a minimum, while anti-nodes occur at points where the wave's displacement is at a maximum. The distance between two consecutive nodes or anti-nodes is equal to half of the wavelength of the standing wave.
