Question

3. What is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.3 m?

Answer 1

• 266.6 Hertz

Step-by-step explanation:

Given :

• Wavelength = 0.3 m
• Wave speed = 80 m/s

We need to find the frequency of the wave

Using formula:

• 
  `{ \boxed{ \sf{F = (v)/( \lambda) }}} \\`

Where,

• F is frequency,
• v is wave speed,
• λ is Wavelength

On substituting the required values, we get:

`\dashrightarrow \sf \: F = (80)/(0.3) \\ \\ \dashrightarrow \sf \: F = 266.6 \: Hz`

Therefore,

• Frequency of the wave is 266.6 Hertz

Answer 2

The frequency of a wave with a speed of 80 m/s and a wavelength of 0.3 m is 266.67 Hz, calculated using the wave speed divided by the wavelength.

To calculate the frequency of a wave when given the wave speed and the wavelength, we can use the formula:

Frequency (f) = Wave Speed (v) / Wavelength (λ)

Given that the wave speed is 80 m/s and the wavelength is 0.3 m, we can substitute these values into the formula:

f = 80 m/s / 0.3 m

f = 266.67 Hz

Therefore, the frequency of the wave with a wave speed of 80 m/s and a wavelength of 0.3 m is 266.67 Hz.
