Find the frequency of a wave of wavelength 2.5m and speed 400 m/s
1 answer
Answers
Answer:The frequency of wave is 160Hz.Explanation:Given that the formula of speed is V = f×λ where V represents speed, f is frequency and λ is wavelength. So first thing, you have to make frequency the subject by dividing wavelength on both sides :[tex]v = f \times λ \: [/tex][tex]v \div λ = f \times λ \div λ[/tex][tex]f = \frac{v}{λ} [/tex]Next you have to substitute the value of v and f into the formula :Let λ = 2.5m,Let v = 400m/s,[tex]f = \frac{400}{2.5} [/tex][tex]f = 160Hz[/tex]
