Title quoted from Mr. Substitute teacher that we had today. I must say he's one of the best substitutes I've had in a long time. Very interesting indeed.
Anyway... HELLO! I'm Jadanet, I couldn't scribe yesterday because I had work afterschool, and wouldn't be able to access a computer until after 10. So here I am today! It's late right now too.. but that's okay because it's the weekend :D
So today what we did in class was a CHAPTER 14 Study Guide booklet. Okay... really it was 3 pages, not a booklet persay.. :) It consisted of a brief summary about all the waves and things related to it that we've been covering for the past week. In the format of "fill in the blanks", we used textbooks to aid us. That took a majority of the class period and at the end of it we went over the answers.
Here are the answers if you couldn't catch them:
1) TYPES OF WAVES
- mechanical, material, electromagnetic, no, particles, matter, 3, perpendicular, motion, parallel, motion, surface, parallel, perpendicular, single, continuous, vibrating, harmonic.
2) THE MEASURES OF A WAVE: FREQUENCY, WAVELENGTH AND VELOCITY
- shortest, motion, cycles, second, hertz, hz, hz, f= 1/T, T, f, wavelength, lamda(λ), high, low, v=λ·f
3) AMPLITUDE OF A WAVE
- maximum, equilibrium, energy.
4) WAVES AT BOUNDARIES BETWEEN MEDIA
- amplitude, frequency, property, equal, equal, incident, transmitted, energy, reflected, most, little, inverted, erect, frequency, amplitude, speed.
5) SUPERPOSITION OF WAVES
- independently, displacement, sum, displacement, superposition, same, greater, shape, size, opposite, zero, destructive interference.
6) STANDING WAVES
- undisturbed, destructive, displacement, constructive, standing, stationary, standing still.
And that's all we did and covered! I'm guessing we'll be going over reflection, refraction, diffraction and interference of waves on Monday. So study hardy for the test on Tuesday!
Scribe on Monday will be "Hi I'm Justus"! :)
