1. What is the difference between longitudinal and transverse waves? Compare and contrast the direction of their movement, movement of a molecule
through the completion of a cycle, and amplitude and wavelength
measurements of each type of wave.
2. Suppose that a wave has a period of 0.03 second. What's its frequency? Be
sure to show the steps for your work.
3. Compare a wave that has a period of 0.03 second with a second wave that
has a period of 1/4 second. Which wave has the greater frequency? Be sure to
show the steps for your work.
4. If a wave has a wavelength of 4.5 meters and a period of 0.007 second, what's
the velocity of the wave? Be sure to show the steps of your work.
5. Using the image below, identify the numbered parts of the wave.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl +4h2o enter the elemental symbol. view available hint(s) is reduced
