Question

Which of the following have quantized values? This question may have more than one correct answer The pitch of a note played on a slide trombone because the pitch varies based on the position of the slide. The pitch of a note played on a flute because the pitch is dependent on the number of holes that are open or closed. The wavelengths of light produced by the heating elements in a toaster because the heat element progresses from heat to red to white in distinct steps. The wind speed on the top of Mt. Everest because the wind varies continuously.

Explanation / Answer

Quantized value means those values that can be expressed as an integer, not a continuous number. Quantized value is a concept where a physical quantity can have discrete values.

1. The pitch of a note played on a slide of a trombone does not have quantized value, it is continuous, does not have discrete values.

2. The pitch of a note played on a flute does have quantized values, the pitch is dependent on the discrete holes that are open or closed.

2. The radiation/wavelength is produced when electrons are excited to upper levels in discrete steps. So it has quantized values.

4. Not quantized, it is continuous.

So, answer is 2 and 3.
