A wave has a wavelength of 0.98 m and travels 2.0x10^2 m in 0.78 s. What is the frequency of the wave?

Respuesta :

Answer:

261.64 hz

Explanation:

speed = distance/ time

s= 200/0.78= 256.41 ms^-1

by using v= (f) x ( lambda)

256.41/ 0.98 = f = 261.64 hz

The frequency of the wave with the given wavelength, traveling the given distance at the given time is 261.6 Hertz.

What is the frequency of the wave?

Wavelength is the distance over which the shapes of waves are repeated.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given that;

  • Wavelength λ = 0.98m
  • Distance traveled d = 2.0×10²m
  • Time elapsed t = 0.78s
  • Frequency = ?

First, we determine the speed.

Speed = Distance / time

Speed = 2.0×10²m / 0.78s

Speed = 256.4m/s

Now, we find the frequency.

λ = v ÷ f

f = v ÷ λ

f = 256.4m/s ÷ 0.98m

f = 261.6s⁻¹

f = 261.6Hz

Therefore the frequency of the wave with the given wavelength traveling the given distance at the given time is 261.6 Hertz.
