Sylvie Snetting: difficult situation. browse onto the search engines. it will help!
Von Houskeeper: challenging problem. lookup in bing and yahoo. that could help!
Rodolfo Merel: Special relativity does not deal with accelerating frames of reference.That comes under general relativity alone.Special relativity deals only with NON accelerating frames ie inertial frames of reference.Hence none of the answers are valid for special relativity."The speed of light in ALL INERTIAL frames of reference, in a vacuum, is c"...Show more
Hugo Pittari: C.OK get this, this is important as it's the fundamental law of physics that prompted AE to come up with his STOR.The speed of light in a vacuum, C, is the same speed in all...all...reference frames. So there are no vacuum reference frames where the SOL is less than C = 299.79E6 m/s....Show more
Jeannetta Gaffigan: "According to special relativity, light in a vacuum would travel at less than 3.0 108 m/s in which ! frames of reference?""A. Frames of reference that are accelerating"Always false, since Special Relativity "does not do" accelerating frames of reference. (I can be extended to some simple straight-line accelerations, but it explicitly states *no acceleration* in its derivation.)"B. All frames of reference"Always true. The actual speed of light is 299,792,458 m/s, which is less than 300,000,000 m/sec.http://physics.nist.gov/cgi-bin/cuu/Value?c"C. No frames of reference"Always false."D. Frames of reference that are not accelerating"Always true, same as B) above.This question is so poorly worded, it is hard to guess what the author would consider a correct answer. "oldprof" is probably correct in his answer choice, and "Andrew Smith" also has a point....Show more
