SolitonHardQuestion 31385

Question

A soliton (solitary wave) maintains its shape while travelling because:

A
It has zero amplitude
B
Nonlinear effects exactly balance dispersion
Correct
C
The medium is perfectly rigid
D
It travels in vacuum

Correct answer

Nonlinear effects exactly balance dispersion

Explanation

In nonlinear media, solitons are self-reinforcing wave packets where the nonlinearity prevents dispersion. Observed in optical fibres, water waves, and plasma physics.
