Abstract: Using the fundamentals of geometrical optics' method to study the interaction between the static field and the photon, the speed of photon in gravitational field is obtained and then the deflection of light and radar echo delay in Reissner-Nordström (R-N) field is discussed.General relativity is verified with a new approach.This method is novel and brief, and it is suitable to other fields.The study of the geometrical optics and metric optics about light propagation in plasma is very hot recently, in principle our new method can also be used in this field.

Key words: radar echo delay, weak gravitational field, Reissner-Nordström metric, deflection of light, coordinate velocity
