One of the early attempts to measure the speed of light was to measure the position of a star located at right angles to the path of the Earth in its orbit (Fig). (a) If the measured angle 8 is found to be between 89°59'39.3/1 and 89°59'39.4, then what would be the range of values for the speed of light? (b) Describe a reasonable method for measuring this angle tothe above accuracy.
