I have a question and the answer, but I need to know how to get to the answer. Thanks
What is the frequency, in hertz, of a sound wave (v=340 m/s) with a wavelength of 0.20 m? answer is 1.7 103 Hz (there is a box symbol after 1.7 and the 3 is superscript)
v = fw
340 = f*0.2
f = 340/0.2 = ??
To find the frequency of a sound wave, you can use the formula:
Frequency = Wave Speed / Wavelength
In this case, the wave speed (v) is given as 340 m/s and the wavelength (λ) is given as 0.20 m. Plugging these values into the formula, we get:
Frequency = 340 m/s / 0.20 m
Dividing 340 m/s by 0.20 m, we find that the frequency is equal to 1700 Hz, or 1.7 x 10^3 Hz.
Note: The notation 1.7 x 10^3 Hz means that we move the decimal point three places to the right to express the frequency in scientific notation.
