Source waves are emitted uniformly in all directions from a point source. The dependence of sound level `beta` in decibels on the distance `r` can be expressed as (a and b are positive constants)

Sound waves are emitted uniformly in all directions from a point source. The dependence of sound level beta in decibels on the radial distance r can be expressed as [Given a and b are positive constants]

Spherical sound waves are emitted uniformly in all direction from a point source. The variation in sound level SL. As a function of distance r from the source can be written as where a and b are positive constants.

Spherical sound waves are emitted uniformly in all direction from a point source. The variation in sound level SL. As a function of distance r from the source can be written as where a and b are positive constants.

A point source that emits wave uniformly in all directions, produces wavefronts that are

IF A is the amplitude of the wave coming from a point source at distance r then

Intensity of sound at a point is its distance from the source

A point source of 2 watt is radiating uniformly in all direction in vacuum. Find the amplitude of electric field at a distance 2m from it-

A source of sound operates at 2.0 kHz, 20 W emitting sound uniformly in all direction. The speed of sound in air is 340 m s^(-1) at a distance of air is 1.2kgm ^(-3) What is the intensity at a distance of 6.0 m from the source ?
