pigment the changes color when exposed to ultraviolet light radiation. The dye in the UV bead is photo chromic that changes color when exposed to UV‚ which is chemical reaction. Review Literature UV‚ or ultraviolet‚ light is an invisible form of electromagnetic radiation that has a shorter wavelength than the light humans can see. It carries more energy than visible light and can sometimes break bonds between atoms and molecules‚ altering the chemistry of materials exposed to it. Ultraviolet-sensitive

Practical 3 Absorption Spectra and the Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by

of colors. While taking the temperature of the visual colors‚ he noticed when he placed the thermometer bulb just beyond the red colors the temperature would raise‚ this was the birth of thermal radiation. There are types of radiations in the electromagnetic spectrum‚ a lot of which we can not see. The little portion that we can see is called light. This spectrum is identified by either short or long wavelength‚ infrared is non-ionizing radiation found in the long wavelength between microwaves and

Effective Induction Training Program We have all started working at places that just expect us to "hit the ground running" and become productive extremely quickly. Many of us will have worked at places that regard an induction as a waste of time‚ or think a quick tour of the building should be sufficient! The benefits of induction training are vast and include: increased retention of newly hire employees‚ improved employee morale and increased productivity. A properly crafted induction plan will

Electromagnetic radiation is produced when charged particles of sufficient energy hit a material.

presented the Maxwell’s equations by combining the works of Lorentz‚ Faraday‚ Ampere and Gauss. He predicted the propagation of electromagnet waves in free space at the speed of light. His theory was accepted 20 years later‚ after Hertz validated electromagnetic wave (wireless) propagation. Hertz demonstrated RF generation‚ propagation and reception in the laboratory. His work then continues by Guglielmo Marconi after 2 decades. He then acquires a method for transmitting and receiving information. Marconi

A personalised induction will always be more effective A personalised induction is the hypnotic induction that is tailored to suit individual people. It can be quite easy to fall into the trap of thinking that one screed will suit all however‚ it must be understood that everybody is different and when trying to induct them into a hypnotic state it means that the screed can be personalised to specific people. Clients can come in all ‘shapes and sizes’ and it is the job of the therapist to identify
