What is the speed of ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?
No, ultrasonic wave do not travel at all in a vacuum.
What is wavelength of 512 hertz sound wave that travels 100 meters through air at STP?
The wavelength is about 67 centimeters, regardless of how far it travels.
What is the wavelength of a sound with a frequency of 18 kHz near the high end of your hearing range?
The wavelength of a sound wave can be calculated by dividing the speed of sound in air (around 343 m/s) by the frequency of the sound wave. For a 18 kHz sound wave, the wavelength would be approximately 19.1 cm.
How do the wavelength of each of these Sound waves compare An instrument plays a pitch of 266 Hz. Another identical instrument plays a pitch of 400 Hz.?
The wavelength of a sound wave is inversely related to its frequency. Since the speed of sound in air is approximately constant, a lower frequency (like 266 Hz) corresponds to a longer wavelength, while a higher frequency (400 Hz) has a shorter wavelength. Specifically, the wavelength of the 266 Hz sound wave will be longer than that of the 400 Hz sound wave.
Suppose you wish to produce a sound wave that has a wavelength of 8 m in room-temperature air What would its frequency be?
For any wave, the wavelength,l = c/f. Rearranging this, f=c/l. The speed of sound at room temperature is about 300 m/s, so an 8 m wave would have frequency of 300 m/s /8 m =37.5 cycles/s, a little bit lower than the E string on a bass guitar, which is the same as the fifth white key on a piano.
What is the wavelength of 350 Hz?
The wavelength is (the speed of the wave) / (350) .
What is the wavelength of a 440 Hz wave in air?
The wavelength of a 440 Hz wave in air can be calculated using the formula: wavelength = speed of sound in air / frequency. The speed of sound in air at room temperature is approximately 343 m/s. Therefore, the wavelength of a 440 Hz wave in air is approximately 0.780 meters.
What is the wavelength of 250Hz?
The wavelength of a 250 Hz sound wave in air is approximately 1.4 meters. Wavelength is calculated by dividing the speed of sound in air (about 343 meters per second) by the frequency of the wave.
What happens to wavelength as a wave leaves the air and enters the perspex?
The wavelength bends forward as it leaves the air and enters the Perspex. The frequency of the wavelength will also increase.
What happens to the wavelength of a wave as it leaves the air and enters Perspex?
The wavelength of the wave decreases as it enters Perspex due to the change in the speed of the wave, according to Snell's Law. The wave slows down in Perspex, causing the wavelength to shorten.
Which characteristic of a light wave must increase as the light wave passes from glass into air?
The wavelength of the light wave must increase as it passes from glass into air. This is because light travels faster in air than in glass, causing the wavelength to stretch out as the wave exits the denser medium.
When a sound wave passes from air into water do you expect the frequency wavelength to change?
The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.
What happens to the wavelength of a sound wave when it travels through water rather than air?
The wavelength of a sound wave decreases when it travels through water rather than air, as sound travels faster in water due to its higher density compared to air. This increase in speed causes the wave to compress more frequently, resulting in a shorter wavelength.
What is the wavelength of 20kHz?
The wavelength of a 20 kHz wave is approximately 15 meters in air. Wavelength can be calculated using the formula: wavelength = speed of sound / frequency.
What is the relationship between wavelength frequency and velocity of sound in air?
The wavelength of a sound wave is inversely proportional to its frequency, meaning higher frequency sound waves have shorter wavelengths. The speed of sound in air is constant at around 343 meters per second, regardless of the frequency of the sound wave. This means that as the frequency of a sound wave increases, its wavelength decreases, but the speed of sound in air remains the same.
What is the wavelength of a 1000 Hz wave?
The wavelength of a 1000 Hz wave in air is approximately 0.34 meters. This can be calculated using the formula wavelength = speed of sound / frequency, where the speed of sound in air at room temperature is approximately 343 meters per second.
What is the frequency of a wave with the wavelength of 3m?
To find the frequency of a wave, you can use the equation: frequency (f) = speed of the wave (v) / wavelength (λ). If the wavelength is 3m and you know the speed of the wave (for example, in air at room temperature it is about 343 m/s), you can calculate the frequency using this equation.
