3 July 2013 Research Questions:
1) if Aurora Borealis, caused by the collision of energetic charged particles and atoms in the high altitude atmosphere, how do these factors affect the Aurora Borealis? For example, the colour(s) of the Aurora Borealis?
2) Since the incident angle of light is equal to the reflected ray, is the 'incident' ray of sound equal to the 'reflection' ray of sound?
3) How long it takes for a tennis ball to lose its "bounce"?
