Melissa Benning Introduction The purpose of the coordination complex lab is to determine the absorbance spectra of complexes based on their color. Every complex has its own color which results from the wavelengths of white light it reflects. The complexes will be compared by the color each reflects and by the energy of the waves each absorbs. The purity of the synthesized complex will also be found. Procedure Part I: Preparation of the Complex A sample of copper sulfate pentahydrate (6.285g)

The electromagnetic spectrum consists of seven different waves. The waves are in the order of how big the wavelength is and its frequency‚ from the biggest to the smallest: Radio waves‚ Micro waves‚ Infrared‚ Visible light‚ Ultra Violet‚ X-rays and Gamma rays. Each of them has their own special use in everyday life. For example‚ to turn on a TV you need to use Radio waves‚ to heat your food you use Microwaves and X-rays are used to look into people’s bodies. Some waves‚ like Radio waves can be as

In transvers waves the motion of the particles is perpendicular to the direction of the energy. In longitudinal waves it they are parallel to each other. Wavelength is the distance a wave has travelled after one cycle and does not change. Amplitude is the distance between the equilibrium and the maximum displacement of

spectrum is determined using spectrophotometer. Spectrophotometer produces a graph of the absorbance spectrum which shows the wavelengths (in nm) that are absorbed by the pigment and that are reflected. The reflected wavelength of chlorophylls a and b reflect the wavelengths of l light that are associated with green‚ which gives them their color. Beta carotene reflects the wavelengths that are associated with orange color‚ and that explains its color. Introduction Chromatography paper can be used to

We can see through the results that there isn’t a normal proportional relationship between the wavelength of the light and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least

Colour vision is the ability of any organism to distinguish different light based on their wavelength of light they reflect .The visual system derives colour by comparing the responses to light from several types of cone receptor in the eyes. Colour enable use to separate object form each other and from their background as different objects tend to have different colour. On the other hand‚ object of the same colour are grouped together. One of the most important functions of the human eye is to

Spectrophotometry‚ a branch of spectrometry‚ is a group of instrumental techniques that measures the atomic and molecular energy levels of a substance [1]. In spectrophotometry‚ the emission and absorption spectra’s wavelengths identify and measure the concentration of a substance. The wavelength at which the substance’s absorbing ions or molecules has a
