PLEASE HELP! Specific hints would help alot
A train blows its whistle to warn traffic of its approach. The sound waves are moving at a speed of 331 m/s. The frequency of the waves is 15 Hz. What is the wavelength?
Wavelength = V * 1/F = V/F = 331/15 = 22.07 m.
Note: 15 Hz means 15 cycles/second.
The wall sockets in our homes are 60 cycles/second(cps).
9
cps).
To find the wavelength, we need to use the formula:
wavelength = speed / frequency
Where:
- Speed is the speed of sound waves, which is given as 331 m/s.
- Frequency is the frequency of the waves, given as 15 Hz.
Plugging in the values:
wavelength = 331 m/s / 15 Hz
Now, let's calculate the wavelength.
