Answer:
0.0714 second
Explanation:
Speed of wave, v = 35 cm/s = 0.35 m/s
wavelength, λ = 2.5 cm = 0.025 m
The time taken by the wave to complete one wavelength is called time period of the wave. It is denoted by T. Its SI unit is second.
The number of vibrations completed in one second is called frequency of the wave. it is denoted by f. Its SI unit is Hertz (Hz).
The relation between the wave velocity, wavelength and frequency is
v = f λ
0.35 = f x 0.025
f = 14 Hz
The relation between frequency and the time period is given by
[tex]T = \frac{1}{f}[/tex]
[tex]T = \frac{1}{14}[/tex]
T = 0.0714 second
Thus, the time taken by a wave to complete one wave is 0.0714 second.
The time it will take for 1 wavelength(which is 1 cycle of the wave) to travel past point X is;
T = 0.0714 s
We are given;
Speed of wave; v = 35 cm/s = 0.35 m/s
Wavelength; λ = 2.5 cm = 0.025 m
Now, we want to find the time it takes for 1 wavelength to travel past point X. This time is also known as period.
Now, the formula for the period is;
T = 1/f
Where f is frequency.
Let us find f from the formula;
f = v/λ
Thus;
T = 1/(v/λ)
T = λ/v
T = 0.025/0.35
T = 0.0714 s
