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,
~Micah K.

Best ResponseYou've already chosen the best response.1I 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.

Best ResponseYou've already chosen the best response.1Radio 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?

Best ResponseYou've already chosen the best response.1Hmm.. 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.

Best ResponseYou've already chosen the best response.1But microwaves use radio waves.

Best ResponseYou've already chosen the best response.1That is how the original device was invented.

Best ResponseYou've already chosen the best response.1"Microwaves are high frequency radio waves" Ok :

Best ResponseYou've already chosen the best response.1In this case, using radio waves would be considered as an "old idea".
