Question

What is the speed of a wave with a 700 Hz frequency and 6 m wavelength Need Help Now

Answer 1

Frequency is the Number of Waves passing through a Point in One Second

Given : The Frequency of the Wave is : 700 Hz

Given : The Wavelength of the Wave is : 6 meter

⇒ In One second 700 waves of Wavelength 6 meter cross the point

⇒ In One second the First wave travels : 700 × 6 meters

⇒ In One second the First wave travels : 4200 meter

⇒ The Speed of the wave is : 4200 m/sec
