Can you please help me with the following three problems. My prof didn't explain them at all. Thank you! 1.X-ray radiation has frequencies from 3.0×1016 to 3.0×1019 Hz, whereas the frequency region for microwave radiation is 3.0×108 to 3.0×1011 Hz. We can say that: 1. The speed of X-ray radiation is higher than or lower than or the same as microwave radiation. 2. The wavelength of X-ray radiation is longer than or shorter than or the same as microwave radiation....
