Biography

I am a 38 year old female with ample experience educating children. I previously hold a Bachelor’s degree in Art (Music to be specific) which helped qualify me into an entry position as a substitute teacher in the department of education, since 2006. Currently, I’m pursuing a degree in Middle and High School Education in the field of Science. I’m easy going, determined and committed to educating children and youth.

Chemistry: The Molecular Nature of Matter and Change

Portions of electromagnetic waves A, B, and C are represented by the following (not drawn to scale): Rank them in order of (a) increasing frequency; (b) increasing energy; (c) increasing amplitude. (d) If wave B just barely fails to cause a current when shining on a metal, is wave A or C more likely to do so? (e) If wave B represents visible radiation, is wave A or C more likely to be IR radiation?
