In physics class, we corrected the test on the supporting arguments of both particle and wave theories of light. It was out of 30 and it was calles Nature of Light II.... here are the corrections :
1. a.) Rectilinear Propagation: Light travels in straight lines, and its very fast.
example: a ball thrown quickly travels straight.
b.) Reflection: angle of reflection equals angle of refraction.
c.) Refraction: Light moves slower on a less dense medium.
2.a.) Rectilinear Propagation:
b.)Reflection: angle of reflection equals angle of refraction
c.) Refraction: light travels in a more dense medium
3.) State 2 properties of light that Newton couldn't explain very well with his particle model.
-Difraction -Partial reflection/ refraction
4.) (about your choosen scientists)
5.)
6.) (c.) wavelength of light
7.) (a.) electromagnetic wave
8.)
9.) Einstein stated that light was not transmitted as a continuous wave. He proposed light was transmitted as a photon and his famous experiment was the photoelectric effect.
10.) wave, then particle.
Alsoo on friday we took down notes :) ....
Kinematics
Scalars - number, unit
-distance
-temperature
- time
- speed
-mass
-energy
Vectors
- number, unit + direction
- position
- displacement
-velocity
- force
- weight
- acceleration
Time
Instantaneous time: clock reading
Time interval: difference between 2 clock readings
After taking down notes we were given a short worksheet and then we corrected it.
....that was all for friday.

Todays class we just did lab. Actually half of the class did lab and others, worked on worksheets that we were given. The lab was just to try and experience how the position time graph goes.
Ohh yeah..... in the end of the class were told to hand in the worksheet that were given for homework last friday. thats pretty much all we did :) kaaay see you all tomorrow!!
THE NEXT SCRIBE : yvanne dandan.
