- During take off the sound intensity level of a jet engine is 120 Dan at a distance of 28 m what is the sound intensity level at a distance of 1.0 km? express your answer with the appropriate unit the answer is not 60What is the wavelength in air at 22° C of a 440 Hz sound?Two waves, one traveling in water and another traveling in air, have the same frequency and the same wavelength. The speeds of the two waves are different because they are in different mediums the are the same because they have the same wavelegth and frequency are same in magnitude but opposite in direction because sound has a harder time going through water are impossible to determine without knowing the densities and temperatures of the two mediums.
- #45) The speed and wavelength of coastal water waves are 4.0 m/s and 6.0 m respectively. When the waves enter a shallower region, the speed decreases to 1.7 m/s. What is the wavelength in the shallower region?The lower frequency limit of hearing for a particular human being is 25.9 Hz. What is the corresponding wavelength for this frequency if the air temperature is 23.1°C? 2-
