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.

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.

It conforms what ever surface its in.
