Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

Data Input Methods Optical data readers The best data input method for printed questionnaires would be Optical Data Readers. Optical Data Readers are a special type of scanning device to be used on documents. Optical Data Readers fall under two categories‚ optical mark recognition (OMR) and optical character recognition (OCR) (Stair‚ R.‚ Reynolds‚ G.‚ 2004). Printed questionnaires which‚ for instance‚ can be used for surveying groups of people regarding a particular subject can utilize OMR through

Scattering in the Earth’s Atmosphere Tony Yuk Hei Chan Abstract Introduction When the sun radiates light to the earth‚ incoming solar radiation often is scattered from its original direction of propagation as it enter earth’s atmosphere. This is due to the scattering effect from different particles in the earth’s atmosphere. When the scattering occur‚ the phase and the polarization of solar radiation are often changed. In this experiment‚ we aimed to investigate the effect of two of the

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which
