Need ! answer the following questions: what causes sound? can you hear in outer space? why or why not? name the three mediums sound waves can travel in? define transverse waves. define longitudinal waves. how is frequency defined in relation to pitch? describe the doppler effect? (worth 2pts) define pitch. define a sound wave how is it caused?

Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly.

a wave vibrating at right angles to the direction of its propagation.

a wave vibrating in the direction of propagation.

People can hear sounds that range from about 20 to about 17,000 hertz. The word that musicians use for frequency is pitch. The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low.

t occurs because the frequency of the sound waves changes as the source of sound moves closer to or farther from the listener. The Doppler effect has several real-world applications. For example, besides police radar, the Doppler effect is used by meteorologists to track storms.

the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

sound wave. ... The pattern of the disturbance creates outward movement in a wave pattern, like waves of seawater on the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source.

Explanation:

What causes sound? it is cause by the mechanical vibrations of various elastic bodies.

Can you hear in outer space? No, you cannot. Sound travels through the vibration of atoms and molecules in mediums such as sir. In space, where there is no air, sound has no way to travel.

Name the three mediums sound waves can travel in? gas, liquid, and solid. Sound waves travel the slowest through gases, faster through liquids, and fastest through solids.

Define transverse waves. A transverse wave is a wave in which particles move perpendicular to the direction of the wave propagation.

Define longitudinal waves. A longitudinal wave is a wave in which the particles move in a direction parallel to the wave propagation.

How is frequency defined in relation to pitch? The pitch of sound corresponds to the frequency at which the air molecules carrying the sound vibrate at. The higher the pitch, the higher the frequency. An increase of one octave in pitch corresponds to a frequency twice as high. An increase of one half-step corresponds to an increase in frequency by a factor of the 12th root of 2 (the number that if raised to the 12th power gives 2).

Describe the Doppler Effect? The doppler effect describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer.

Define pitch. Pitch can be described as the sensation of a frequency. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.

Define a sound. A sound wave is a pressure wave. They can be thought of as fluctuations in pressure with respect to time. Sound waves are transverse waves. It is caused when an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate creating a chain reaction. This “chain reaction” movement, called sound waves

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.
