A typical explanation for the evolution of blond hair was the people of Northern Europe’s vitamin D absorption and synthesis. As Europeans were subjected to a seasonal deficiency of sunlight‚ which is required for vitamin D synthesis‚ they developed an adaptation for lighter

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

Abstract: In this lab‚ our concept is to find the extinction coefficient “ε” for a specific sunscreen with a sun protection factor (SPF)‚ we are using brand: NO-AD SPF 15 for this experiment‚ our extension coefficient “ε” value is to be 482.04 cm2/g. Objective: Our objective with this experiment is to find the relation of sun block with the extension coefficient by measuring the absorbent rate of UV rays the sunscreen can absorb. And how it can absorb harmful waves that emit from the sun.
