Which of the following can be chosen to analogously represent the behavior of a particle?

(a) Metal rod

(b) String

(c) Elastic rubber

(d) Glass rod

This question was addressed to me during a job interview.

My query is from DE Broglie’s Explanation of Bohr’s Second Postulate of Quantisation topic in section Atoms of Physics – Class 12

Best answer
Right option is (b) String

To elaborate: A string is used to represent the behavior of a particle analogously to the waves traveling on it.  Particle waves can lead to standing waves held under resonant conditions. When a stationary string is plucked, it causes several wavelengths to be excited. But, we know that only the ones which have nodes at the ends will survive.
