• Need to know how to calculate acceleration.
• Be able to state a factor which increases thinking distance
• Need to revise circuits, like adding a voltmeter to measure potential difference across a component.
• The complete law of reflection
• Showing reflection accurately
• Showing how the size of a gap in a barrier affects the effect of diffraction. (drawing)
• Showing the accurate path of a beam of light through water then air
• Definition of critical angle.
• Calculating critical angle
• Showing how information is transmitted through an optical fibre ACCURATELY
i need to remember unit one formula
You've identified what you've got wrong but you haven't said how to improve. You need to give specific examples of each of these things:
ReplyDeleteeg "• Need to know how to calculate acceleration. = a=v-u/t"
eg "• The complete law of reflection = i=r"
etc
ps. Please turn off word verification for comments!
