can please somebody check my answer:
Q. A tuning fork produces a sound that has a wavelength of 136 centimetres. What is the frequency of the tuning fork? (Take the speed of sound to be 340 metres per second.)
A. f= velocity/wavelength
f= 340/1.36
f=250Hz
You got it!
To check your answer, you can use the formula for the frequency of a wave:
frequency = velocity / wavelength
Given that the speed of sound is 340 meters per second and the wavelength is 136 centimeters, you first need to convert the wavelength to meters:
136 centimeters = 136/100 meters = 1.36 meters
Now you can substitute the values into the formula:
frequency = 340 m/s / 1.36 m
frequency = 250 Hz
Your answer of 250 Hz is correct!
