sound waves move through some liquid at a speed of 1500 m/s. If the wavelength is 3 m, what is the frequency of the wave?
a)500 Hz
b)4500 Hz
c)0.002 Hz
d)1503 Hz
v = fλ
plug in your numbers
Thank you!
The answer is A for future people.
To find the frequency of a wave, we can use the formula:
Frequency (f) = Speed of wave (v) / Wavelength (λ)
In this case, the speed of the sound wave is given as 1500 m/s, and the wavelength is 3 m. Plugging in these values into the formula, we get:
f = 1500 m/s / 3 m
Simplifying:
f = 500 Hz
Therefore, the frequency of the wave is 500 Hz. Hence, the correct option is (a) 500 Hz.
