Question 1 Report
A transverse pulse of frequency 9 Hz traves 4.5m in 0.6 s. Calculate the wavelength of the pulse.
Answer Details
The formula for the speed of a wave is given by:
v = λf
where v is the speed of the wave, λ is the wavelength, and f is the frequency.
We are given the frequency of the pulse as 9 Hz and the time it takes to travel a distance of 4.5 m as 0.6 s. We can use these values to calculate the speed of the pulse as follows:
v = d/t = 4.5 m/0.6 s = 7.5 m/s
Now, we can use the formula v = λf to calculate the wavelength of the pulse:
λ = v/f = 7.5 m/s / 9 Hz = 0.83 m
Therefore, the wavelength of the pulse is 0.83 m. Answer option (C) is correct.
