Light and sound are two very different phenomena. However, both exhibit wave characteristics, such as frequency, for sound waves, when the frequency changes, the pitch is affected. Using the diagrams above as a reference, determine how visible light is affected by changes in frequency

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
