What is electrolysis? What is a stroboscope? With the help of a diagram, explain the construction and working of a LASER. Write down the properties of a LASER. What is line spectra and continuous spectra and what are their applications?
Spectral lines are discrete points in the frequency domain used to digitize the spectrum (remember that a computer cannot store a continuous analog function, it must break any data into discrete points). The entire signal is divided up among these 6000 data points (i.e., spectral lines). For...
What are Spectra types? What is a spectrum ? What are Spectral lines? What is the Michelson and Morley experiment? Explain the condition for two waves to be in phase. What causes a disturbance that results in a wave? What is the nature of ripples produced on the surface of the water?
Line Spectra When continuous spectrum, like in a rainbow, comes from white light, line spectrum is evident in colored compounds. Light spectrum only has a few wavelengths (not all) or lines. Atoms tend to absorb some wavelengths when electromagnetic radiation is passed through them which display...
EDS (yellow) and WDS (grey) spectra from the same material, the 10x better resolution for WDS clearly shows even the most closely spaced X-ray peaks for analysing complex samples or detecting minor or trace elements. My analytical journey started with using EDS. Please igno...
The time domain is better for many measurements, and some can be made only in the time domain. For example, pure time-domain measurements include pulse rise and fall times, overshoot and ringing. Why measure spectra? The frequency domain also has its measurement strengths. We have already ...

Spectrum analysis, which mathematically identifies spectral lines and their intensities, is often performed electronically. This typically uses a mathematical technique known as Fast Fourier Transform (FFT). Another widely used form of spectroscopy is nuclear magnetic resonance (NMR) spectroscopy. These are...
MALE PROFESSOR: Now astronomy didn't really, uh, balloon, into the science it is today until the development of spectroscopy.Spectroscopy is basically the study of spectra and spectral lines of light, and specifically for us, the light from stars. It makes it possible to analyze the light ...
