A periodic pulse travels a distance of 20.0m in 1.00s. If its frequency is 2.0 x 103Hz. Calculate the wavelength.
Answer Details
The speed of a wave is given by the product of its wavelength and frequency. Therefore, we can use the formula:
v = λf
where v is the speed of the wave, λ is the wavelength, and f is the frequency.
In this problem, we are given the frequency of the wave as 2.0 x 10^3 Hz and the distance it travels in 1.00 second as 20.0 m. We can calculate the speed of the wave as:
v = distance/time = 20.0 m/1.00 s = 20.0 m/s
Now, we can rearrange the formula to solve for the wavelength:
λ = v/f = 20.0 m/s / 2.0 x 10^3 Hz = 1.0 x 10^-2 m
Therefore, the wavelength of the wave is 1.0 x 10^-2 m.
Answer: 1.0 x 10^-2 m
