Question

please help with physics. thank you

An angle marking is like a meter stick marking. The marking of 1.2m on a meter stick only means an object is 1.2m long if the object starts at zero meters. If it starts at 0.2 meters then the object is really 1.0 meters long. You will be making angle calculations from angle markings in a similar fashion. Given a green marking of 204 degrees and a straight-on marking of 252 degrees, how much has the light bent? degrees. Given lambda = 424.5[nm], then what is 1/lambda^2? [nm^-2] (Report your answer in Scientific Notion 0.00E-00 with three significant figures, or N/A if there is no answer.) Given lambda^-2 = 5.55E-06[nm^-2] and theta = 39.9[degrees], then what is the index of refraction to the nearest? (Take the phi in the equation for n in the manual to be 60 degrees.)

Explanation / Answer

   as per chegg guidelines i can answer only one.Please raise different question for others

6)light bent will be in this case is

theta=252 degrees-204 degrees

=48 degrees
