Under what condition can focal length on 2 sides of a lens vary?

Three characteristics of musical sound= loudness pitch and quality.              ORR pleasant smooth continuous loe sound level etc etc

Reverbration- If the reflector of an echo is at a distance of less than 17m ,the orginal sound mixes up with the reflected sound.Due to repeated reflections at the reflecting surface the sound gets prolonged.This effect is known as reverbration.

Anyone wanted the definition of reverbration here it is!
