Homework Answers
Q1)option a is correct.
Light waves change phase by 180° when they reflect from the surface of a medium with higher refractive index than that of the medium in which they are travelling.so it will be partially transmitted
according
to the HOMEWORKLIB RULES I should have done only first question in
case of multiple questions.but here I have done four .please ulpoad
others separately or mark the required one
Sorry for inconvenience

How much work must we do on an electron to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces (e = 1.60 times 10^-19C) 1.60 times 10^-17 J -1.60 times 10^-17 J 1.6 J -1.6 J This cannot be determined because we do not know the distance traveled.
