a note of frequency 2000Hz has a velocity of 400 ms-1. calculate the wavelength of the note
Answer Details
The formula for calculating wavelength is:
wavelength = velocity / frequency
Given that the frequency of the note is 2000 Hz and the velocity is 400 m/s, we can substitute these values into the formula and get:
wavelength = 400 / 2000 = 0.2 meters
Therefore, the wavelength of the note is 0.2 meters.
To understand this better, you can think of the wavelength as the distance between two consecutive peaks or troughs of the sound wave. In this case, the note has a frequency of 2000 Hz, which means it vibrates 2000 times per second, producing sound waves that travel at a velocity of 400 m/s. The wavelength is the distance that these sound waves travel in one complete vibration cycle, which in this case is 0.2 meters.
