a sound wave has a frequency of 1000 hertz and wavelength of 50 cm how long will it take to travel a distance of 500m?

Answer:
HEY!! THERE ↓
Step-by-step explanation:
The speed of the sound, distance travelled and the time taken relationship is given as follows.
Speed of sound, v = Distance Travelled×Timetaken ----eqn 1
With the given values of wavelength = 50 cm = 0.5 m and frequency =1000 Hz, the speed of the wave is calculated as follows.
Speed of sound,v = Frequency(ν)×Wavelength(λ) -- equation 2
That is, v = ν×λ
= 1000Hz×0.5m
= 500m/s
Substituting the value of the speed of sound in eqn 1 gives the time taken for the sound wave to travel a distance of 500 m.
→→ Time taken = speed of sound/ Distance travelled
= 500ms / 500m
= 1 second .
Hence, the time taken for the sound wave to travel is 1 second.
Hope this GOONA!! help you.
