Do sound waves always travel in straight lines explain?
No, Sound is a pressure wave not a linear wave, the waves radiate spherically from their point of origin. Also as a pressure wave, it travels in a medium and if that medium is moving the sound wave propagation can be modified by that movement (bent). They also behave like sea waves impinging on a headland and can be bent round objects in their path in complex ways.
Which wave is a body wave?
A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves. Each type of wave shakes the ground in different ways.
What are four different things that can happen to the waves when they meet an obstacle?
In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.
Describe ways that echoes are used in measurement?
The speed of sound is the distance travelled by the sound waves in the time between the original sound and the echo. For a direct echo, the distance travelled is double the distance to the reflecting surface.
How are surfaces different from body waves?
A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves. Each type of wave shakes the ground in different ways.
What is the smallest unit of sound wave energy?
The smallest unit of sound wave energy is the phonon. The phonon and the photon and the electron can in some ways all behave like a small particle.

What is similar between the sound wave and the light wave?
Both are ways to transport energy from point a, to point b. Both sound and light waves have a speed, wavelength and frequency. Both can be diffracted, reflected and refracted, as those are properties of waves.
Do soundwaves die?
Yes, in a sense. Since they were never living, they cannot die, but they can disappear in 2 ways.1). Since sound waves are actually just air molecules bumping into each other, eventually, the sound wave dissipates enough that it is indistinguishable from normal molecular motion2). The sound wave reaches the border between the atmosphere and space, where there are no air molecules and therefore no sound waves.
what are two ways in which ultrasound technology produces images?
By using sound in frequencies that reflect off body tissues. By measuring the time it takes for the reflected sound wave to be detected. :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) (I made a smiley face man :D)
What are four ways a 'wave' can be changed?
wavelength, amplitude, frequency, and wave speed
In what ways are sound waves like ocean waves?
Sound waves are like ocean waves because it resembles an ocean wave with crests (peak) and troughs (valleys). The crests indicate regions of high pressure and the troughs, low pressure.
Two ways to determine wave speed?
you can determine it by the wavelenght and the period of the wave and the frequencey
What are 3 ways a wave can be described?
Butt
What are types of wave according to the mosyon of the particle?
Wave propagation is any of the ways in which waves travel.With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves.For electromagnetic waves, propagation may occur in a vacuum as well as in a material medium. Most other wave types cannot propagate through vacuum and need a transmission medium to exist
