Which of the following correctly compares UV rays and x-rays?

A) X-rays have the same wavelength as UV rays.
B) UV rays have the same energy as X-rays.
C) X-rays have a higher frequency.
D) UV rays have lower energy.

Respuesta :

UV rays and X-rays are electromagnetic waves (do not require material medium for transmission). They are part of the electromagnetic spectrum and travel with the speed of light (3×10^8 m/s). In this case i believe the answer is C, X-rays have a higher frequency compared to UV rays.
The total amount of energy before and after a chemical reaction is the same. Thus, energy is A. conserved. B. created. C. destroyed. D. the same as mass.
