Question

The table shows measurements of some properties of a sound wave in water and in air.Fill in the table using what you know about the relationship between wavelength, frequency, and speed.

Answer 1

v= λ f

Where:

v = speed

λ= wavelenght

f= frequency

Water:

λ = v/f = 1500 m/s / 200 hz = 7.5 m

Water:

v= λ f = 3.75 m x 400 HZ = 1500 m/s

Air

f = v/ λ = 343 / 10 = 34.3 HZ

Air

λ = v/f = 343 /17.15 = 19.6 m
