Question
Statement 1: The to-and-fro motion of a body is called vibration.Statement 2: Sound is always produced by a vibrating body.
Solution
Statement 1: The statement is correct. The to-and-fro motion of a body is indeed called vibration. This is a type of motion that repeatedly moves back and forth. It can occur in various things like a plucked guitar string, a ringing telephone, or a swinging pendulum of a grandfather clock.
Statement 2: This statement is also correct. Sound is produced when something vibrates. The vibration causes the air around it to move and these air particles, in turn, create a chain reaction. They bump into the particles close to them, which then bump into

Fill in the blanks. Choose from the following words, some may be used more than once, others not at all: Doppler, shift, higher, frequency, lower, relative, absolute, reflections, refractions, blood, water, ultrasound, infrasound, movement If a sound source is moving relative to an observer, the sound appears to undergo a change in . If the source is approaching an observer then they will perceive the sound to have a frequency than when it was emitted at the source. The opposite is also true, with a sound from a receding source perceived to be in frequency. This phenomenon of apparent change is called the effect. The change in frequency itself is called the Doppler . The magnitude of the Doppler shift depends on the speed of the source towards or away from the observer. The Doppler effect also applies to of sound off a moving interface. The Doppler effect can be used with to detect and measure the of anatomical structures within the body. For example, the rate of flow through arteries and veins, or through the heart can be measured. The ultrasound beam is reflected off cellular components in the blood, and the observed shift is used to determine the rate of blood flow along the line of sight.
