If the frequency of a sound wave is 250 hertz and its wavelength is 1.36 meters, what is the wave's velocity?

340 m/sec

Explanation:

A wave speed is usually defined as the distance that a wave covers in a given amount of time. It is commonly represented in terms of numbers of meters a wave moves per second.

Given that,

Frequency of sound wave, f = 250 Hertz

Wavelength, λ = 1.36 meters

Mathematically,

⇒ Wave velocity (speed) = Frequency × Wavelength

⇒ v = 250 × 1.36

⇒ v = 340 m/sec

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
