5. a sound wave produced by a clock that is a distance of 515 m away is heard 1.50 s later.\na) what is the speed of sound?\nb) the sound wave has a frequency of 426 hz. what is the period?\nc) what is the wavelength of the sound wave?
Answer
Explanation:
Step1: Calculate the speed of sound
The formula for speed is (v=\frac{d}{t}), where (d = 515\space m) and (t=1.50\space s). [v=\frac{515}{1.50}] [v = 343.33\space m/s]
Step2: Calculate the period
The formula for period (T) in terms of frequency (f) is (T=\frac{1}{f}). Given (f = 426\space Hz) [T=\frac{1}{426}] [T=0.00235\space s]
Step3: Calculate the wavelength
The formula for wavelength (\lambda) is (\lambda=\frac{v}{f}). We know (v = 343.33\space m/s) and (f = 426\space Hz) [\lambda=\frac{343.33}{426}] [\lambda = 0.806\space m]
Answer:
a) (343.33\space m/s) b) (0.00235\space s) c) (0.806\space m)
