What is the beat frequency produced when the following two waves are sounded together?

x₁ = 10 sin (404πt - 5πx), x₂ = 10 sin (400πt - 5πx)

A particle in SHM is described by the displacement equation x(t) = A cos (ωt + θ). If the initial (t = 0) position of the particle is 1 cm and its initial velocity is π cm/s, then what is its amplitude? (The angular frequency of the particle is πs^-1.)

The equation of a simple harmonic wave is given by y = 5 sin π/2 (100t - x), where x and y are in metres and t is in seconds. The period of the wave will be

The frequency of a tuning fork is 256 Hz. The velocity of sound in air is 344 ms^-1. The distance travelled (in metres) by the sound during the time in which the tuning fork completes 32 vibrations is

When both the listener and the source are moving towards each other, then which of the following is true regarding the frequency and wavelength of the wave observed by the observer?

How can you describe a periodic motion

Frequency of the periodic motion is

A particle is executing two different simple harmonic motions mutually perpendicular to different amplitudes and having a phase difference of π/2. The path of the particle will be

The factor determining the pitch of a tuning fork is
