Can someone please help me with this question?
You are going to invent a new device that people can use instead of a microwave oven to warm up leftovers. Which type of electromagnetic wave would be most useful to investigate?
gamma rays
X–ray
radio waves
infrared waves
Thanks,

I know that it isn't B, and I believe that gamma rays are too dangerous. Therefore, it must be C or D. Correct me if I'm wrong.

Radio waves are used in microwaves, and if I want to create a unique device, different from a microwave, that probably means that C isn't an option either. So it must be D. Am I right?

Hmm.. You can hardly warm food using radio wave (consider its frequency, the energy is pretty low)... A and B should be ruled out, and you've got the reason.

But microwaves use radio waves.

That is how the original device was invented.

"Microwaves are high frequency radio waves" Ok :

In this case, using radio waves would be considered as an "old idea".

Okay. So the answer is D?
