Two tuning forks when sounded together produced 4 beats/sec. The frequency of one fork is
256
. The number of beats heard increases when the fork of frequency 256 is loaded with wax.
When two tuning forks are sounded together 4 beats per second are heard the frequency of the fork B is 384?
When two tunning forks A and B are sounded together , 4 beats per second are heard . The frequency of the fork B is
384 Hz
. When one of the prongs of the fork A is filled and sounded with B , the beat frequency increases , then the frequency of the fork A is. When one of the prongs of A filed , its frquency increases …
When two tuning forks are sounded together 4 beats are heard?
When two tuning forks are sounded together 4 beats are heard per
second
. One tuning fork is of frequency 346 Hz. When its prong is loaded with a little wax, the number of beats is increased to 6 per second.
When two tuning forks A and B sounded together produce 4 beats per second?
Waxing
implement A would mean the frequency of A has reduced such that it again produces 4 beats per second with B. Thus, it’s now less than B by 4Hz and initially it had been above B by 4Hz. So, the correct answer is “Option C”.
When two tuning forks 1 and 2 are sounded simultaneously 4 beats per second?
When two tuning forks (fork 1 and fork 2) are sounded simultaneously, 4 beats per second are heard. Now, some tape is attached on the prong of the fork 2. When the tuning forks are sounded again, 6 beats per second are heard.
When two tuning forks A and B are sounded together?
If two tuning forks A and B are sounded together, they
produce 4 beats per second
. A is then slightly loaded with wax, they produce 2 beats when sounded again. The frequency of A is 256.
When two tuning forks A and B are sounded together 5 beats?
Two tuning forks A and B when sounded together, produce 5 beats
per second
. The frequency of B is 512 Hz. It is observed that if one prong of A is slightly scraped, then the number of beats increases Determine the frequency of A.
What is the beat frequency when following two waves are sounded together?
The beat frequency is
always equal to the difference in frequency of the two notes that interfere to produce the beats
. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected.
What happens when a tuning fork is filed?
when the prongs
are loaded, their inertia increases, resulting in decrease of vibrational frequency
. similarly, when the mass is removed by filing the prongs, their inertia decreases resulting in increase of vibrational frequency.
What are beats the result of?
Beats are caused by
the interference of two waves at the same point in space
. This plot of the variation of resultant amplitude with time shows the periodic increase and decrease for two sine waves.
How do you find the beat frequency of three sources?
Beat frequency= n1-n2 (n=frequency)
. I know that beat frequency is the difference in the frequencies of two superposing notes. But here 3 wave frequencies are given. The differences are 3, 4 and 7 Hz.
When following two waves are sounded together?
When two waves occupy the same point,
superposition
occurs. Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves.
Can two waves with different frequencies interfere?
No
; wave interference takes place whenever two waves of any frequency, same, nearly the same or widely different interact. An air molecule next to your ear, for example, can only respond to the sum of all the different sound waves reaching it at any moment.
Does filing increase frequency?
(1) Loading or filing of one prong of known or unknown (by wax) tuning fork, so frequency changes (
decreases after loading, increases after filing
).
What happens to frequency when tuning fork is waxed?
Hint:When a tuning fork is loaded with wax, the frequency of
the tuning fork decreases
. Here, the beats produced per second remain the same before and after loading wax into the unknown tuning fork. The beats produced per second refers to the difference between the frequencies of the two tuning forks.
