The deflection of light rays from a star located near the edge of the Sun during a total solar eclipse (0.875 “) is considered as experimental proof of the truth of the theory of relativity. What other physical phenomenon causes a comparable deviation of light rays from the star? How should an observational experiment confirmed the conclusions of the theory of relativity?
Refraction at the edge of the Sun’s disk also causes the star’s light rays to deflect. To minimize the effect of refraction, observations to confirm the theory of relativity are carried out in the radio and microwave ranges. The required accuracy of angular measurements is obtained using ultra-long baseline radio interferometers.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
