String 1 has twice the length, twice the radius, twice the tension and twice the density of another string 2. The relation between the fundamental frequencies of 1 and 2 is String 1 has twice the length twice the radius twice the tension and twice the density of another string 2. The relation between the [...]

A sufficiently long closed organ pipe has a small hole at its bottom . Initially, the pipe is empty. Water is poured into the pipe at a constant rate . The fundamental frequency of the air column in the pipe A sufficiently long closed organ pipe has a small hole at its bottom . Initially [...]

If λ1,λ2 and λ3 are the wavelengths of the waves giving resonance with the fundamental, first and second overtones respectively of a closed organ pipe. Then the ratio of wavelengths λ1:λ2:λ3 is first and second overtones respectively of a closed organ pipe. Then the ratio of wavelengths λ1:λ2:λ3 is If λ1 λ2 and λ3 are [...]
