Which of the following statements is true? a. x-rays have higher frequencies than microwaves. b. uv rays have higher frequencies than gamma rays. c. gamma rays have lower frequencies than microwaves d. infrared rays have lower frequencies than radio waves.

I would say the answer is A because X-rays have more radiation just enough for you not to get effected by it, while microwaves if they do not have those type of little black holes sheet on the plastic door then it would effect you thats why you shouldn't get too close to the door.
I think.
Hope this helps!
