A tuning fork produce 2 beats when sounded with one oscillator of frequency 514 Hz, and produces 6 beats with the other oscillator of frequency 510 Hz. The frequency of tuning fork
Two waves of lengths 50 cm and 51 cm produced 12 beats per second. The velocity of sound is-
Two identical flutes produce fundamental notes of frequency 300 Hz at 27°C. If the temperature of air in one flute is increased to 31°C, the number of the beats heard per second will be
To obtain beats, the maximum difference in the frequencies of two sources is :
26 tuning forks are arranged in a line having beat frequency of 4 between two successive tuning forks. If frequency of last tuning fork is 3 times that of 1st tuning fork then find the frequency of 1st tuning fork :
A tuning fork arrangement (pair) produces 4 beats/sec with one fork of frequency 288 cps. A little Wax is placed on the unknown fork and it then produces 2 beats/sec. The frequency of the unknown fork is :
A tuning fork of known frequency 256 Hz. makes 5 beats per second with the vibrating string of a piano. The beat frequency decreases to 2 beats per second when the tension in the piano string is slightly increased. The frequency of the piano string before increasing the tension was
Two sound waves with wavelengths 5.0 m and 5.5 m respectively, each propagate in a gas with velocity 330 m/s. We expect the following number of 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. If the frequency of fork 1 is 200 Hz, then what was the original frequency of fork 2?
When beats are produced by two progressive waves of the same amplitude and of nearly the same frequency, the ratio of maximum loudness to one of the waves will be n, Where n is :
Transverse waves can propagate -
The waves in which the particles of the medium vibrated in a direction perpendicular to the direction of wave motion is known as -
A medium can carry a longitudinal wave because it has the property of-
The property of a medium necessary for wave propagation is –
Superposition is the main characteristic of
Which of the following are longitudinal waves ?
A longitudinal travelling wave transports
The equation of a wave travelling in a string can be written as y = 3 cosπ(100 t – x). Its wavelength is -
When a wave enters from air to any medium, then what remains unchanged -
If two waves of same frequency and amplitude superpose to produce resultant of the amplitude of either wave, then their phase difference is-
Necessary condition for interference is that-
A wave y = 10 sin (ax + bt) is reflected from a dense medium at an origin. If 81% of energy is reflected then the equation of reflected wave is-
A wave shown by the equation y = a sin (ωt + Φ) is totally reflected by a denser medium, then the following will change -
Two wire of length 1m and 2m respectively and mass 150 gm. and 300 gm. respectively. If the tensions are same on both the wires, the ratio of velocities of transverse waves will be –
