Physics - Sound Wave Question with Solution | TestHub

The explanation of the statements are given below

(i) In meled's experiment p$\sqrt{T}$=constant.

$⟹p^{2}T$=constant

Hence, this statement is correct.

(ii) In Kundt's experiment distance between two heaps of powder is$\raisebox{1ex}{$\lambda $}\!\left/ \!\raisebox{-1ex}{$2$}\right.$

Hence, this statement is correct

(iii) Quink's tube experiment is related to interference

hence the option is incorrect

(iv) Echo phenomena are related to the reflection of sound.

So, this statement is correct
