Velocity of ultrasonic wave using acoustic grating?
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.
What is the instrumental difference in IR and FTIR?
In FT-IR, an interferometer is used to collect a spectrum. This interferometer has a source, a beam splitter, two mirrors, a laser, and a detector. One part of the beam is transmitted to a moving mirror and the other is reflected to a fixed mirror. In Dispersive-IR, there is also a source and mirrors, but the source energy is sent though a sample and a reference path, through a chopper to moderate energy that goes to the detector, and directed to a diffraction grating. The diffraction grating separates light into separate wavelengths and each wavelength is measured individually.
Who studied DNA using x-ray diffraction?
Rosalind Franklin
What observations indicate that visible light has a wavelength much shorter than a centimeter?
One observation is that visible light can easily pass through small openings, like the gaps between leaves or the gaps between two fingers. If visible light had a wavelength much larger than a centimeter, it would not be able to pass through these small openings. Additionally, visible light can be easily diffracted by a small obstacle, like a hair or a thin wire. This diffraction behavior indicates that visible light has a much smaller wavelength than a centimeter.
What happens to signal's wavelength as its frequency increases?
Using the relationship C = n lambda C - velocity of light, n-frequency of radiation and lambda- the wavelength. So as frequency increases definitely its wavelength decreases.
How can you observe the spectrum in the lab?
You can split white light using a prism or a diffraction grating.

How do you break white light without a prism?
You can break white light without a prism by using a device called a diffraction grating. A diffraction grating has thinly etched lines; you can see this effect by noticing the rainbows you see from the bottom of a DVD.
What was Henry Moseley's experiment?
In 1913, by using x-ray spectra obtained by diffraction in crystals, he found a systematic relation between wavelength and atomic number, Moseley's law.
What are the key applications for laser diffraction?
There are numerous applications for laser diffraction. Their key applications include using them as part of a particle sizing technique, and using them in laser diffraction spectroscopy.

Explain if transmit baseband signal directly in a wireless system and why?
An antenna must be the order of magnitude of the, wavelength signal in size to be effective. Using only baseband transmission, FDM could not be applied and (Path loss, penetration of obstacles, reflection, scattering and diffraction. All the effects depend onthe wavelength of a signal.
A crystal has an interplanar spacing of 98.2 pm. Using first order diffraction, what is the X-ray wavelength required to produce a reflection with an angle of 17.5 degrees?
Using d sin π = nπ, d=98.2pm, n=1, π=17.5ΒΊ 98.2sin(17.5ΒΊ) = 1π π=29.53pm

What is the formula for period using wavelength and speed?
Period = wavelength/speed
What does it mean purity angle?
It is a measure of the spectral heterogeniety of a peak based on the comparison of spectra over all the peak, using the spectral contrast angle.
