At first glans, this paper would be off-topic, but it would hopefully contribute to physical science as it suggests novel methods for measuring speed of light emitted from moving objects. Speed of light has been measured by various methods and to current knowledge is believed to be constant. These techniques include accurately known measurement methods of the day; e.g. cavity resonator, radio and laser interferometry etc. and are persistently revised. Despite the fact that there exists some controversy regarding the limit of speed of light, but there also methods like FEL (A free-electron laser or FEL, is a type of laser whose lasing medium consists of very-high-speed electrons moving freely through a magnetic structure). Proposed method is based on a conception of measuring the speed of light from a moving frame which according to the principal of special relativity would be a constant quantity in vacuum and is independent of the frame and its relative velocity whether the light is received or emitted. In spite of the theoretical part i.e. relativity and Doppler Effect and the fact that Michelson and Morley experiment doesn’t measure the speed of light directly, this method suggests an applied measurement which needs to be tested. In addition another method based on fringe shift is suggested on a rotating Michelson-Morley platform. In fact the Sagnac effect has already shown a non-null result [1] as it is done on a rotational platform, but this method is somewhat different as one of the mirrors has a slower linear/angular velocity then the other one.
