The ultrasonic waves generated with the help of a quartz crystal inside the liquid in a container sets up standing wave pattern consisting of nodes and anti-nodes. The nodes are transparent and anti-nodes are opaque to the incident light. In effect the nodes and anti-nodes are acts like grating(a setup of large number of slits of equal distance) similar to that of rulings in diffraction grating. It is called as acoustic grating or aqua grating. Hence, by using the condition for diffraction, we can find the wavelength of ultrasound and thereby the velocity of sound in the liquid medium.

To find wavelength of spectral line using diffraction grating?
To find the wavelength of a spectral line using a diffraction grating, you can use the formula: dsin(θ) = mλ, where d is the spacing of the grating lines, θ is the angle of diffraction, m is the order of the spectral line, and λ is the wavelength of the light. By measuring the angle of diffraction of the spectral line and knowing the grating spacing, you can calculate the wavelength of the light.
How would you compute the resultant velocity given a linear velocity and an angular velocity?
by using trig. So draw a triangle out with the given information. for example 1 line is 12m/s, another line is Um/s (u for unknown) and one line is resultant velocity. add your angle in and use trig to work out what you want.
What is critical velocity in fluid dynamics?
Critical velocity is that The Liquid Air flow in narrow pipe constatly.
Why would filtered rain water fail to work at all in an ultrasonic humidifier when distilled works fine?
Filtered rain water may still contain impurities or minerals that can interfere with the operation of an ultrasonic humidifier. Distilled water has been stripped of these impurities through the distillation process, making it a better choice for use in ultrasonic humidifiers to avoid mineral buildup and potential damage to the device.
What will be the final velocity if the acceleration of 10 meters per second squared is sustained for 7 seconds?
It will depend upon the initial velocity of the body. If 'u' be the initial velocity of the body, then the final velocity will be: v = u + at (v = final velocity, a = acceleration, t = time) i.e., v=u+10*7 = (u + 70) m/sec. If u=0 (i.e the initial velocity be zero) then final velocity, v=70 m/sec.

How can you find volumetric properties using ultrasonic velocity?
Volumetric properties, such as density or compressibility, can be determined using ultrasonic velocity measurements by analyzing the speed of sound waves as they travel through a substance. By applying the appropriate equations and principles of ultrasonic physics, researchers can correlate the velocity of sound with the material's volumetric properties. This method is commonly used in scientific research and industrial applications to characterize materials and understand their physical properties.

Determation of wave lenght using diffraction grating?
The wavelength of light can be determined using a diffraction grating by measuring the angles of the diffraction pattern produced by the grating. The relationship between the wavelength of light, the distance between the grating lines, and the angles of diffraction can be described by the grating equation. By measuring the angles and using this equation, the wavelength of light can be calculated.
Explain how ultrasonic waves can be produced in the laboratory?
Ultrasonic waves can be produced in the laboratory using a device called an ultrasonic transducer. The transducer converts electrical energy into mechanical vibrations, which generate the ultrasonic waves. These waves can be used for various applications, including medical imaging, cleaning, and material testing.
How do you calculate wavelength from diffraction grating?
You can calculate the wavelength of light using a diffraction grating by using the formula: λ = dsinθ/m, where λ is the wavelength of light, d is the spacing between the grating lines, θ is the angle of diffraction, and m is the order of the diffracted light. By measuring the angle of diffraction and knowing the grating spacing, you can determine the wavelength.

What is a sentence using the word ultrasonic?
My toothbrush uses ultrasonic vibrations to help clean my teeth and gums.The sound of an ultrasonic dog whistle can be heard by dogs, but not by humans.
To find wavelength of spectral line using diffraction grating?
To find the wavelength of a spectral line using a diffraction grating, you can use the formula: dsin(θ) = mλ, where d is the spacing of the grating lines, θ is the angle of diffraction, m is the order of the spectral line, and λ is the wavelength of the light. By measuring the angle of diffraction of the spectral line and knowing the grating spacing, you can calculate the wavelength of the light.
Can an ultrasonic wave be produced by using speakers?
no Because ultrasonic sound waves are not audible and it is not possible to create that much loudness in normal speakers.
Why do you use a non conducting medium for determination of velocity of ultrasonic wave?
Because different conductive media (e.g., air, water, steel, etc.) have different effects on the overall speed of the wave. In order for there to be a specific baseline measurement of the wave's velocity, it must be done in a non-conductive medium to eliminate the value of any conductive medium from the equation.
How can you observe the spectrum in the lab?
You can split white light using a prism or a diffraction grating.
