Sound Waves length measurement

In summary, in this conversation, the discussion revolves around two sources, A and B, emitting sound of a certain wavelength. The sound is detected at a point away from the sources, with source A being a distance d away and source B having to travel a distance of 3.7λ. The maximum sound intensity at the observation point depends on the largest value of the wavelength, in terms of d. To find the frequency of the emitted sound, the equation for constructive interference of waves, |d1-d2|= n*(Wavelength), can be used.

Homework Statement



Two sources, A and B, emit a sound of a certain wavelength. The sound emitted from both sources is detected at a point away from the sources. The sound from souce A is a distance d from the observation point, whereas the sound from source B has to travel a distance of 3.7λ. Take v to be 340 m/s.

a) What is the largest value of the wavelength, in terms of d, for the maximum sound intensity to be detected at the observation point?

b) If d = 14.1 m and the speed of sound is 340 m/s, what is the frequency of the emitted sound?

How you have attempted at the solution?
 
  • #3
I have attempted at the solution by using the equation |d1-d2|= n*(Wavelength) n=0,1,2... ,which is the equation constructive interference of waves.
However, i am not sure that i'll going to use this formula for the maximum sound intensity
 

Related to Sound Waves length measurement

1. How is the length of a sound wave measured?

The length of a sound wave is measured by its wavelength, which is the distance between two consecutive points of similar displacement, such as two consecutive peaks or troughs.

2. What unit is used to measure the length of a sound wave?

The unit used to measure the length of a sound wave is meters (m). However, in some cases, it may also be measured in centimeters (cm) or millimeters (mm).

3. Can the length of a sound wave be changed?

Yes, the length of a sound wave can be changed by altering its frequency. Higher frequency waves have shorter wavelengths, while lower frequency waves have longer wavelengths.

4. How does the length of a sound wave affect its pitch?

The length of a sound wave directly affects its pitch. Shorter wavelengths (higher frequency) produce higher-pitched sounds, while longer wavelengths (lower frequency) produce lower-pitched sounds.

5. Why is measuring the length of a sound wave important?

Measuring the length of a sound wave is important because it allows us to understand and analyze the characteristics of a sound, such as its frequency and pitch. This information is crucial in fields such as acoustics, music, and communication.
