Adjustable Frequency
Highly Accurate Radio Frequency Signal Generator
Toronto, Canada - GAO Instruments (www.GAOInstruments.com)has released a CPU-controlled radio frequency signal generator operating over a frequency range of 300kHz to 300MHz. It is commonly used in research and development and production testing of AM/FM receivers, civil-band transceivers, radio remote -controlled devices and wireless telephones.
This radio frequency signal generator, model A0400001, offers non-volatile RAM which can store a hundred samples of data. It features both an RS-232C and an IEEE-488 interface. The signal generator provides a highly stable time base to satisfy the most stringent requirements in terms of time base aging and accuracy. The signal generator can be controlled remotely by a computer or other instruments. In open mode, its RF output is adjustable between -8dBμ and120dBμ at an accuracy of ±1.5dB. This generator consumes 35W maximum power.

Can someone help me with Waves and Sound?
Tuning fork A has a frequency 256 Hz and is sounded at the same time as another 256 Hz tuning fork, B, is loaded to reduce its frequency. If the beats are heard at the frequency of 10 Hz. What is the frequency of fork B?
I dun really know which equation to use...SO confusing
Question 2: If the speed of sound in air is 344 m/s what will the 1st resonant lengths in an adjustable closed air column be, if a tunning fork with a frequency of 440 Hz is struck at the open end?
I need to know what formula I have to use......=___='''
You have stated that the tuning fork B is loaded and has a lesser frequency than that of A.
Let the frequency of B be N and you know that N is lesser than 256 Hz.
Beat frequency is the difference between the two frequencies.
Therefore 256 - N = 10 ( given).
Or N = 246 hz.
For your second question:
Velocity = frequency X wavelength.
In a closed tube the first resonant length is obtained when the length is one fourth of the wavelength.
Therefore L = 4 x l.
Or V = 4 N l where N is the frequency and l is first resonating length.
344 = 4 x 440 x l.
l = 344 / 1760 = 0.195 m = 19.5 centimeter.
