What are finite waves?

(a) Waves with large perturbations

(b) Sound waves

(c) Weak waves

(d) Waves with small temperature fluctuations

The question was posed to me by my school principal while I was bunking the class.

The doubt is from Finite Waves topic in chapter Unsteady Wave Motion of Aerodynamics

Right choice is (a) Waves with large perturbations

Easiest explanation: The traveling waves have small perturbations in ambient conditions having small changes in pressure, density etc. Such waves are weak waves but finite waves have large perturbations at ambient conditions.
