If the time between the flash and the sound of a fireworks bang is 4 seconds, and the speed of sound is 340 m/s, we can calculate the distance of the event using the formula:
Distance = Speed × Time
Given that the time is 4 seconds and the speed of sound is 340 m/s, we can substitute these values into the formula:
Distance = 340 m/s × 4 s = 1360 meters
Therefore, the event is approximately 1360 meters away.
To calculate the wavelength of the sound, we need additional information such as the frequency of the sound wave. The wavelength (λ) is related to the speed of sound (v) and the frequency (f) by the equation:
λ = v / f
Without knowing the frequency, it is not possible to determine the wavelength of the sound.
