On the Light tab, once again investigate briefly all the phenomena you explored with water and sound above. Describe any similarities in your results for light. Specifically describe wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

d they tend to lose electrons and become cations.

explanation:

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
