I basically understand the idea of the changes in phases of interference in thin films but i was hoping for a better explanation. i understand that the thickness of the lens effects the the exit phase but i don't know why PLEASE HELP! Thank you
The voltage of an AC source is given by the equation v=180sin377t where v is the instantaneous voltage and t is in seconds. (a) what is the rms value of the voltage? (b) what is the frequency of the ac source? (c) if this voltage is connected to a 40 ohm resistor, find the equation that...
