An important predictor of whether a stock price will go up is its track record of momentum.  Price trends tend to persist, so it's worth looking at them when it comes to a share like Reflex Advanced Materials. Over the past six months, its share price has underperformed the Toronto Stock Exchange 300 Composite Index by -69.22%.

The PE ratio (or price-to-earnings ratio) is the one of the most popular valuation measures used by stock market investors. It is calculated by dividing a company's price per share by its earnings per share.

Raman scattering is defined as the scattering of photons by excited molecules at higher energy levels. It is also known as the Raman effect. The photons are inelastically scattered, which means that the kinetic energy of an incident particle is either lost or increased and is composed of Stokes and anti-Stokes portions.

C.V. Raman discovered Raman spectroscopy in 1928 to study the vibrational, rotational, and low-frequency modes of the molecules. It finds application mainly in chemistry to get the information related to fingerprints.

LASER, considered intense monochromatic light in Raman scattering, can give rise to scattered light, which contains one or more sidebands offset by rotational or vibrational energy differences. The sidebands produced include frequencies containing information about the scattering medium, and hence they are used in remote sensing.

similar to Rayleigh scattering, Raman scattering also depends on the polarizability of the molecules. The intensity of Rayleigh scattering is about 10−3 to 10−4 compared to the intensity of the exciting source. The photon’s energy and the state of the molecule after the scattering events are unchanged. In Raman scattering, the frequency of photons presents in the monochromatic light changes when interacted with the vibrational states, or modes, of a molecule.

Raman spectrometer is an instrument that consists of one or more single-coloured light sources and lenses and filters to focus the light and to differentiate the reflected and scattered light, respectively. A prism is used for splitting the light into its components which has a detector to detect the weak light. Later the spectrum is obtained on the monitor to analyze the information.

Inelastic scattering of photons is similar to the concept of an inelastic collision, which states that the total microscopic kinetic energy is not conserved. In an elastic collision, the transfer of kinetic energy occurs, but the scattering will still be inelastic like in Compton scattering.

The degree of freedom (DOF) is defined as a number of independent parameters that determine the configuration of the physical system. Following is the degrees of freedom formula:

With the help of the Raman scattering, one can easily say why the sky is blue. This depends on the scattering of blue light because of the presence of the air molecules in the atmosphere. Learn more about applications of Physics concepts with BYJU’S.

The difference between the incident photon and the scattered photon is known as the Raman shift. When the energy associated with the scattered photons is less than the energy of an incident photon, the scattering is known as Stokes scattering. When the energy of the scattered photons is more than the incident photon, the scattering is known as anti-Stokes scattering.

The PE ratio can be seen as being expressed in years, in the sense that it shows the number of years of earnings which would be required to pay back the purchase price, ignoring inflation. So in general terms, the higher the PE, the more expensive the stock is.

To analyse the Raman effect, the wavelength of the scattered photon is converted to wavenumber. These wavenumbers are plotted on the x-y plane. The wavenumbers are taken along the x-axis and the Raman intensity is taken on the y-axis. The difference between the wavenumbers and the intensity is known as the Raman spectrum.

For Raman scattering, 3 N is the DOF (for any given chemical compound), where N is the number of atoms in the compound 3 N is DOF because each atom moves in x, y, and z-direction ie; they possess translational, rotational, and vibrational motion.

The principle behind Raman spectroscopy is that the monochromatic radiation is passed through the sample such that the radiation may get reflected, absorbed, or scattered. The scattered photons have a different frequency from the incident photon as the vibration and rotational property vary. This results in the change of wavelength,, which is studied in the IR spectra.

Raman scattering produces scattered photons with a different frequency depending on the source and the vibrational and rotational properties of the scattered molecules. Raman spectroscopy works on the principle of Raman scattering. It is used to study materials by chemists and physicists. In the olden days, to record spectra, a mercury lamp and photographic plates were used; in modern days, lasers are used. Sir CV Raman was awarded the Nobel Prize for Physics in the year 1930. C V Raman, along with his student K S Krishnan, discovered Raman’s scattering.
