Can for ultrasound wave travel long distance in air?
no
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 is the relationship between wavelength frequency and velocity of sound in air?
For any wave phenomenon, the product of (wavelength) x (frequency) is always the wave speed.
What is the wavelength of a wave that has a frequency of 1.0x10-2Hz?
1.0 x 10-2 = 0.01 If the wave is a sound wave in air, then its wavelength is (343/0.01) = 34,300 meters. (about 21.3 miles) If the wave is an electromagnetic wave in space then its wavelength is (299,792,458/0.01) = 29,979,245,800 meters. (about 18,628,200 miles)
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
What is the wavelength of 34000Hz ultrasonic wave in air?
f, frequency: 680Hz (Hertz, cycles per second);c, speed of sound in air : 343 m/s;find λ, wavelength.using c = λ * f; therefore: λ = c / fλ = c / f = 343 / 680 = 0.5m
Can for ultrasound wave travel long distance in air?
no
Is ultrasound a transverse or longitudinal wave?
Sound, at least in gases like air, can only propagate as a longitudinal 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 is the relationship between wavelength frequency and velocity of sound in air?
For any wave phenomenon, the product of (wavelength) x (frequency) is always the wave speed.
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 is the wavelength of a wave that has a frequency of 1.0x10-2Hz?
1.0 x 10-2 = 0.01 If the wave is a sound wave in air, then its wavelength is (343/0.01) = 34,300 meters. (about 21.3 miles) If the wave is an electromagnetic wave in space then its wavelength is (299,792,458/0.01) = 29,979,245,800 meters. (about 18,628,200 miles)
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
What happens to the wavelength of a wave as it leaves the air and enters Perspex?
it stays the same
What happens to the wavelength of a sound wave when it travels through water rather than air?
the wave length of sound increases
What is the wavelength of a 440 Hz wave in air?
For 440 Hz: λ = about 423.37 miles.
What is the wave length of 42800 HZ?
We use 42800 Hz now, and not cps. The wavelength can be calculated, when the medium is known. It may be air and then it is ultrasound. Wavelength lambda = Speed of sound cdivided by frequency f. Speed of sound c is 343 meters per second at a temperature of 20 degrees Celsius or 68 degrees Fahrenheit.
