Question

a water wave of wavelength 6.0 cm and frequency 4.0 Hz travels over the surface of a pond. what is its speed in m/s​

Answer 1

GivEn that:

◕ Wavelength = 6.0 centimetres

◕ Frequency = 4.0 Hz

To calculaTe:

◕ Speed of water wave

SoluTion:

◕ Speed of water wave = 0.24 m/s

Using ConcEpts:

◕ Formula to convert centimetres into metres.

◕ Formula to calculate speed if wavelength and frequency is given.

UsiNg Formulas:

◕ 1 cm = 1/100 metres

◕ Speed = Wavelength × Frequency

Full SolutioN:

~ Firstly let us convert centimetres into metres by using suitable formula!

→ 1 cm = 1/100 metres

→ 6 cm = 6/100 metres

→ 6 cm = 0.06 metres

~ Now let us find out the speed by using suitable formula!

→ Speed = Wavelength × Frequency

→ Speed = 0.06 × 4

→ Speed = 0.24 m/s $\:$
