                                    3. Calculate the wavelength of asound wave whose frequency is220 Hz and speed is 440 m/s ina given medium |

Answer»  Formula -Velocity = Wavelength × Frequency Using the above mentioned formula,v = λ × nwhere λ denotes Wavelength and n denotes frequencyGiven,v = 440 m/secn = 220 Hzλ = ?v = λ × n440 = λ × 220=> λ = 440 / 220=> λ = 2WAVELENGTH (λ) = 2 m  |
