Identify how the air particles move as sound waves travel away from the speaker.Hint: Some of the particles in the simulation are coloured red to make it easier to observe their movements.They travel away from the speakerThey move back and forth in the same direction as the wave motionThey move back and forth at right angles to the wave motionThey move randomlyI'm not sure

16 In a sound wave the air particles travel from the source outwards

Sound is a longitudinal wave which means that the air molecules move in a direction

Sound travels in air ifA particles of medium travel from one place to another B there is no moisture in the atmosphere C disturbance moves D both particles as well as disturbance travel from one place to another

A pair of speakers separated by distance d = 0.630 m are driven by the same oscillator at a frequency of 678 Hz. An observer originally positioned at one of the speakers begins to walk along a line perpendicular to the line joining the speakers as in the figure below. (Use v = 343 m/s.)Two speakers are side by side, with one speaker on the left and one on the right. The speakers are separated by a distance d and emit sound waves in the same direction. A man stands directly in front of the speaker on the right but a distance x away from the speaker.(a) How far must the observer walk before reaching a relative maximum in intensity? m(b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity? m

The model shows that the microphone turns voice sounds into electrical signals. To achieve this, part of the microphone moves quickly back and forth in response to sounds.Determine what this tells us about the nature of sound.Sound is a type of energy that travels as wavesSound is the flow of air from one place to anotherSound is a type of electrical signal that flows through airI'm not sure
