How do you find the speed of a sound wave with frequency?

The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.

How long will it take for a sound wave of 30cm wavelength and 1.5 kHz frequency of Travelling a distance of 2.5 km?

Thus sound will take 2.1 s to travel a distance of 1.5 km. Describe with the help of a diagram, how compressions and rarefactions are produced in air near a source of sound.

How long will it take for a sound wave of 25 cm wavelength and 1.5 kHz frequency to travel a distance of 1.5 km?

Wavelength = 25 cm = 0.25 meters. If the sound travels 375 meters in one second, How much time will it take to travel 1500m? Therefore the sound wave will take 4seconds to travel 1.5 kms.

How do you calculate the speed of sound waves?

SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s. You have calculated the speed of sound!

How do you find frequency when given wavelength and speed?

Speed is distance over time, so v = λ / T. The frequency, f, is 1/T, so the equation relating wave speed, frequency, and wavelength is v = f λ .

How do you calculate the speed of sound in a water wave?

In a fluid, the speed of sound depends on the bulk modulus and the density, v=√Bρ. The speed of sound in a solid the depends on the Young’s modulus of the medium and the density, v=√Yρ.

When the frequency of sound increases the wavelength and period?

Period is defined as the time for one full wave to pass, thus f(Hz)=1T(s) So period will fall if frequency rises. Secondly, the wave equation, v=f×λ so if v remains constant any increase in frequency must cause a reduction in wavelength. So wavelength decreases as frequency increases.

What is the speed of sound in water?

about 1,480 meters per second
Sound travels faster in water than in air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about 1,480 meters per second.

What is the frequency and wavelength of a sound wave?

A sound wave has a frequency of 2 kHz and wavelength 35 cm. How long will it take to travel 1.5 km? Was this answer helpful?

What is the relationship between frequency period and wavelength?

The number of these vibrations per second is called the frequency, which is measured in hertz. The period is the duration of time in one vibration or cycle and is measured in seconds. It is the reciprocal of the frequency. The wavelength is the distance over which the wave’s shape repeats.

Is sound a wave or a compression?

The sound is a wave. If a string of a violin or a harp vibrates back and forth, it is compressing and expanding the surrounding air, thus producing a sound. The high-pressure regions are called compressions and the low-pressure regions are called rarefactions.

How do longitudinal waves transmit sound energy?

In longitudinal waves, the molecules in the air move parallel to the motion of the wave. They compress in the same direction as they travel. These waves travel from sound sources and transmit the energy of the voice or vibrating string. Note that the air does not move when the sound travels through it — only the vibrations move.
