SUMMARY
The discussion centers on the relationship between the energy of incident light and the amplitude of transmitted light through a glass sheet that transmits 70% of the incident light's energy. The correct calculation for the ratio of the amplitude of transmitted light to the amplitude of incident light is derived from the principle that intensity is proportional to the square of the amplitude. Therefore, the correct answer is 0.84 (C), calculated as the square root of the transmitted energy ratio (0.7), which results in an amplitude ratio of approximately 0.84.
