The light transmission through the suspension and the oxygen concentration were then measured. light meter oxygen meter The results were used to plot the absorption spectrum and the action spectrum for each strain of alga. Fig.1.2 shows these spectra. strain A strain B absorbance absorption spectra 400 500 600 700 wavelength of light / nm rate of photosynthesis action spectra 400 500 600 700 wavelength of light / nm Fig.

XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

UNIT 1 Modern Physics 1.1 CLASSICAL PHYSICS Newtons laws of motion are the basis of the most elementary principles of classical physics. Equations based on these laws are the simplest and they are suitable for solution of simple dynamical problems‚ such as the motion of macroscopic bodies‚ Lagranges equations‚ Hamiltons equations and Hamiltons principle are also fundamental principles of classical mechanics‚ because they are consistent with each other and with Newtons laws of
