Question

What is the wavelength of a wave that has a speed of 350 Meters/second and a frequency of 140 hertz?

____ meters​

Answer 1

• 
  `\lambda = 2.5 \: m`

Step-by-step explanation:

To find:-

• The wavelength of the wave.

Answer:-

We are here given that , the speed of a wave is 350m/s and has a frequency of 140Hz . We are interested in finding out the wavelength of the wavelength of the wave .

As we know that, wavelength, frequency and speed are related to each other as ,

`\longrightarrow\boxed{ v = \lambda \\u} \\`

where,

• 
  `v` is the speed of the wave.
• 
  `\lambda` is the wavelength of the wave.
• 
  `\\u` is the frequency of the wave.

On substituting the respective values, we have;

`\longrightarrow 350 m/s = \lambda * 140Hz \\`

`\longrightarrow \lambda =(350)/(140) m \\`

`\longrightarrow \boxed{\boldsymbol \lambda = 2.5 \ m} \\`

Hence the wavelength of the wave is 2.5 m .
