Beats

After loading the prongs of $A$ with some wax and then sounding it with $B, 4$ beats are produced per second. What is the frequency of the tuning fork $A$? Given: On sounding tuning fork $A$ with another tuning fork $B$ of frequency $384 \mathrm{Hz}, 6$ beats are produced per second.

What is the frequency of the tuning fork in $\mathrm{Hz}$? If an accurate and reliable audio oscillator is used to standardise a tuning fork. When the oscillator reading is $514 \mathrm{Hz}$, two beats are heard per second. When the oscillator reading is $510 \mathrm{Hz}$, the beat frequency is $6 \mathrm{Hz}$.

If two tuning forks $A \text{\& }B$ give $4 \mathrm{beats} {\sec }^{-1}$ with each other, on loading $A$ with wax, $2 \mathrm{beats} {\sec }^{-1}$ are given. If frequency of $A$ is $256 \mathrm{Hz}$, then frequency of $B$ is

Two waves each of loudness $L$ superimpose to produce beats. The maximum loudness of beats will be

Two tuning forks have frequencies $450 \mathrm{Hz}$ and $454 \mathrm{Hz}$ respectively. On sounding these forks together, the time interval between two successive maximum intensities will be _____.

Two sound waves of wavelength $2 \mathrm{m}$ and $2.02 \mathrm{m}$ produce $15$ beat in $3 \mathrm{seconds}$ in a medium. The velocity of sound in that medium is

Two tuning forks have frequencies $300 \mathrm{Hz}$ and $308 \mathrm{Hz}$. When they are sounded together, after hearing the maximum sound, how long will it take to hear the first minimum sound?

Consider a source of frequency $X \mathrm{Hz}$. In an experiment with $250 \mathrm{Hz}, 270 \mathrm{Hz}$ sources, the source produces $8 \mathrm{beats}/\mathrm{s}, 12 \mathrm{beats}/\mathrm{s}$, respectively. Find $X=?$

For which of the following cases, does the phenomenon of beats can take place?

Musicians make use of which phenomenon with their musical instruments?

Two tuning forks $\mathrm{A}$ and $\mathrm{B}$ are sounded together and it results in beats with frequency of $4$ beats per second. When $\mathrm{A}$ is loaded with wax, they again produces $4$ beats per second. If frequency of $\mathrm{A}$ is $256 \mathrm{Hz}$, then the  frequency of $\mathrm{B}$ is

When two waves of almost equal frequencies ${\nu }_1$ and ${\nu }_2$ reach at a point simultaneously, the time interval between successive maxima is

Pulse rate of a normal person is 75 per min. The time period of heart is

A student holds a tuning fork oscillating at 170 Hz. He walks towards a wall at a constant speed of $2m{s}^{-1}$ . The beat frequency observed by the student between the tuning fork and its echo is (Velocity of sound $=342m{s}^{-1}$ )

For production of beasts the two sources must have

Statement - 1: In case of beats, intensity of sound at some positions in space remains maximum and at others, it remains minimum

Statement - 2: Beats are formed due to superposition of sound waves of unequal frequencies.

Consider two sound sources ${\mathrm{S}}_1$ and ${\mathrm{S}}_2$ having same frequency 100 Hz and the observer O located between them. All the three are moving with same velocity in same direction. The beat frequency as heard by the observer is
