Include two other factors Chapter 17 says the speed of sound can depend on. The relationship between the speed of sound, its frequency, and wavelength is the same as for all waves: v = f , v = f , 14.1. Add your answer and earn points. . Sound can be modeled in terms of pressure or in terms of displacement of molecules. So, transfer of sound energy occurs faster. The speed of sound in a particular medium depends on temperature and pressure of that medium. In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. Lightning and thunder But the speed of sound is dependent on the temperature. But some of the energy is also absorbed by objects, such as the eardrum in Figure 14.5, and some of the energy is converted to thermal energy in the air. The speed of mechanical waves, like sound and seismic, depends on the mechanical properties of the medium. v = 0.35 m 2000 Hz = 700 m/s. MCQs from CBSE Class 9 Science Chapter 12: Sound. The sound can travel in air when: (a) Particles of medium travel from one place to another. For a heavy object, the terminal velocity is generally greater than a light object. Get the Brainly App Download iOS App Related Topics . Sound is a disturbance of matter (a pressure wave) that is transmitted from its source outward. Sound travels slower in colder air. Get the Brainly App Download iOS App For example, the speed of sound in air at 0 0 C is 331 m s -1 . Speed of light in air and empty space is a fundamental constant, whereas speed of sound depends heavily on the properties of the medium.

The speed of sound is the distance travelled per unit time by any sound. What does the intensity of sound depend upon? 1 See answer Fairy1108789 is waiting for your help. The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. and the temperature of the gas. Substituting the values in the equation, we get. Answer: The speed of sound in air at constant temperature does not vary with pressure. Speed of sound is maximum in solids and least in gases as particles are closer in solids. Note that the sound speed C 0 is artificially low to accentuate the effects of the medium. c=. Speed of sound is used for describing the speed of sound waves in an elastic medium. Speed of Sound waves Vocab. The speed s, in feet per second, of sound in air depends on the temperature t of the air in degrees Celsius and is given by the following. 7. Daniel R. Blume/CC-BY-SA 2.0. Aluminium. Propagation is represented both by rays (black) and wavefronts (red). For example, the speed of sound decreases when it passes from solid to gaseous state of a given medium. Record the outdoor temperature that day. Brainly.ph. So temperature, humidity (if non liquid medium) and pressure are also factors as they impact the density and viscosity of the medium, especially if the sound wave propagates t. (b) There is no moisture in the atmosphere. The speed of sound depends on the temperature, stiffness, and density of the medium the sound travels through. The speed of the sound wave is 340 m/s. 10 terms. Definition. (c) Disturbance travel from one place to another. The magnitude of terminal velocity depends on the weight of the falling body. The only meaningul analogue would be dt/dr, it would not be called speed, and when relativity is taken into account it will have interesting .

Pressure 3.Density(velocity of sound is inversely proportional to square root of density) 4.Humidity(Humid air have. Calculate the speed of sound by dividing the speed that the sound traveled (from Step 6) by how long it took to travel that distance (from Step 7). Answer: Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. The more dense the material is the slower the speed of sound. On Earth, the speed of sound at sea level assuming an air temperature of 59 degrees Fahrenheit . In any medium, if the temperature increases, the speed of sound also increases and vice versa. which a sound wave travels depends upon the type of medium (air, water, rock, etc.) 17.

The speed of sound in air depends on the type of gas and the temperature of the gas. Speed of sound depends upon the density (density is defined as mass per unit volume) of medium (it increases with increase in density of mediums). c =. This points will help you. At a temperature of 819.45, we get a speed of sound of 662.6 m/s. Science Chapter 16 Section 1-2. The human ear is sensitive to frequencies between 20 Hz and 20 kHz. This depends on the characteristics of the medium through which the propagation takes place. (Enter a number. ramabhai4321 ramabhai4321 21 seconds ago English Secondary School What does the intensity of sound depend upon? In this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. Solution: We know that the speed of sound is given by the formula: v = . Q1. izvoru47 and 18 more users found this answer helpful. The amplitude of a sound wave decreases with distance from its source, because the energy of the wave is spread over a larger and larger area. While not negligible, this is not a strong dependence. A free online speed of sound calculator. Answer (1 of 9): Speed of sound depends primarily on the density and viscosity of the medium through which it propagates. ramabhai4321 is waiting for your help. The speed of sound in air at constant temperature remains the same with the increase in pressure. 5,050 m/s. (Enter a number. The time taken by the sound wave to travel a distance of 1.5 km can be calculated as follows: Time = Distance Travelled/ Velocity. Diamond. Solution: Repeat this experiment on days that have very different temperatures. On Earth, the atmosphere is composed of mostly diatomic nitrogen and oxygen, and the temperature depends on the altitude in a rather complex way. Explain why the speed of sound is faster in solids than in gases. 2: Find out the pressure if sound travels through a medium having a density 0.05 KPa and speed of sound is 400 m/s. heart outlined. Therefore, the sound wave can not possibly move through the gas at a speed greater than that of the individual molecules themselves, and in fact must move at a lower speed than that due to the . (Round your answers to two decimal places. How does temperature affect the speed of sound? A sound wave moving through a gas requires a small scale bulk movement of gas molecules back and forth as pressure at any locations builds or falls. The speed of sound is influenced by several factors, including medium, density and temperature. The speed of sound in air is approximately figured out by the formula.
