X-ray radiation falls in the wavelength region of 1.00×10-11 to 1.00×10-8 meters. What is the frequency of X-ray radiation that has a wavelength of 1.00×10-11 m?
Frequency = sec-1
Answer:- frequency = 3.00 * 1019sec-1
Solution:-
since we know that,
frequency * wavelength = speed of light
frequency = speed of light / wavelength .......(1)
speed of light = 3.00×108 ms-1
wavelength = 1.00×10-11 m
from equation (1)
frequency = 3.00×108 ms-1 / 1.00×10-11 m
frequency = 3.00 * 1019sec-1

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....
