Sound two tuning forks of slightly different
frequency. First sound each one separately and then the sound both
at the same time. Notice the beats when you sound both tuning forks
at the same time.
Describe the sound of the beats.
Homework Answers
Let the frequency of fork 1 be f1 and the frequency of fork 2 be f2.when sound at different times we hear the individual frequencies.But when sound at same time we hear the sound that is a result of interference of two waves,the frequency of such waves is called beat frequency.
Beat frequency f= (f1-f2)
The sound of beats is loud at the places of constructive interference and soft at the destructive interference.

Question 5 1 pts Tuning fork A has a frequency of 440 Hz. When A and a second tuning fork B are struck simultaneously, four beats per second are heard. When a small mass is added to one of the tines of B, the two forks struck simultaneously produce two beats per second. The original frequency of tuning fork B was 436 Hz. 432 Hz. 444 Hz. 448 Hz 438 Hz.

You have 2 tuning forks in your hands; one plays the note D (297 Hz) and the other plays the note A (220 Hz). Your classmate plays a third fork with an unknown note and listens to the new combined frequency. Assuming that you can measure the combined frequency like 275 Hz when all three forks are played simultaneously, which of the following notes is most likely to correspond to the mysterious tuning fork a. C (264 Hz) b. F...

Lab 12. Sound Waves and Beats Introduction Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal. Using a Microphone and an interface, you can explore the properties of common sounds. The first property you will measure is the period, or the time for...
