Explanation:

f = frequency of the sound wave = 680 hertz

λ = wavelength of the sound wave = 0.5 meters

v = speed of sound wave

we know that , speed of sound wave is given as

speed of sound wave = frequency of sound wave x wavelength of sound wave

v = f λ

inserting the above values in the formula above

v = (680 hertz) (0.5 meters)

v = 340 meter/second

hence the speed of sound wave comes out to be 340 meter/second
