What are beats answer?
Beats are
the periodic and repeating fluctuations heard in the intensity of a sound
when two sound waves of very similar frequencies interfere with one another.
What do you mean by beats?
Beat, in physics, the pulsation caused by the combination of two waves of slightly different frequencies. … The resulting sound is alternately soft and loud—that is, having
characteristic pulsations
, or throbs, called beats.
What are beats Class 11?
Class 11 Physics Waves. Beats. Beats. Beats is the
phenomenon caused by two sound waves of nearly same frequencies and amplitudes travelling in the same direction
.
What are beats give the theory of beats?
Explanation: A wave not only travels in space but it also propagates through time, so
if the two waves can produce interference by overlapping in space they should also produce an interference pattern when they overlap in time
, this phenomenon is called beats.
What are beats state any two applications of beats?
Application of beats:1) Beats are used in tuning musical instruments. 2)Beats can be used to adjust the vibrating length between the two bridges,in Sonometer Experiment. 3)
Beats can be used to find the frequency of the given tuning fork
. 4)Beats can be used in detection of harmful gases in mines.
What are beats name the basic phenomenon due to which beats are produced?
(i) When two sources of sound having slightly different frequencies are made to vibrate simultaneously, the intensity of the resultant sound varies producing periodic maxima and minima. This phenomenon responsible for their formation is
the interference of waves
.
What are period of beats?
Periods of beats:
The time interval between two successive maxima or minima (waxing or waning)
is called the period of beats. Frequency of Beats: The number of beats heard per second is called the frequency of beats.
What is the formula of beats?
| f b Beat frequency | f 1 Frequency of 1 st wave | f 2 Frequency of 2 nd wave |

What are beats Toppr?
When two different objects vibrate at different frequencies, there is a fluctuating sound
, this sensation is known as beats. In other words, when two sound waves having slightly different frequencies reach your ear, then you are able to hear fluctuating sound (alternate soft and loud sound).
Why is it called a beat?
The term comes from the noun
beat in the sense of an assigned regular route or habitual path
, as for a policeman. By analogy, the beat of a reporter is the topic they have been assigned for reporting.
What type of word is beat?

about beauty and makeup
. The verb to beat refers to the application of one's makeup. As an adjective beat means someone either applied their makeup well, or just applied a lot of it.
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.
What are beats and its uses?
Uses. Musicians commonly use
interference beats objectively to check tuning at
the unison, perfect fifth, or other simple harmonic intervals. Piano and organ tuners even use a method involving counting beats, aiming at a particular number for a specific interval.
What are the applications of Doppler effect?
The Doppler effect is used in some types of radar,
to measure the velocity of detected objects
. A radar beam is fired at a moving target — e.g. a motor car, as police use radar to detect speeding motorists — as it approaches or recedes from the radar source.
