A water wave has a frequency of 6 Hz and a wavelength of 3 m. (a) What is the period of these waves? (b) What is the wave veloci
1 answer:
The period or time duration of these waves is 0.16 sec. While the wave velocity is 18m/sec.
<h3>What is Wavelength?</h3>Wavelength may be defined as the space between equivalent points in the contiguous cycles of a waveform signal propagated in the area or along a wire.
The time duration of these waves is calculated by the given formula:
T = =
= 0.16 seconds.
The velocity is calculated by the given formula:
V= Wavelength × Frequency = 6Hz × 3m = 18m/sec.
Therefore, it is well described above.

<h3><u>Calculating time taken by it to stop (t) :</u></h3>By using the second equation of motion,
→ v = u + at
- v denotes final velocity
- u denotes initial velocity
- t denotes time
- a denotes acceleration
→ 0 = 5 + (-5/6)t
→ 0 = 5 - (5/6)t
→ 0 + (5/6)t = 5
→ (5/6)t = 5
→ t = 5 ÷ (5/6)
→ t = 5 × (6/5)
→ t = 6 seconds
→ Time taken to stop = 6 seconds
