Infrared wave cooking vs microwave radiation

Click For Summary
SUMMARY

Microwave radiation cooks food faster than infrared waves due to differences in penetration ability and interaction with materials. While infrared waves have a higher frequency, which typically suggests greater penetration, this is not universally applicable. The discussion highlights that penetration ability varies by frequency and material, exemplified by radio waves penetrating wooden walls while light does not. Understanding these principles clarifies why microwaves are more effective for cooking.

PREREQUISITES

I have learned that penetration ability increases with frequency. But why can microwave cook faster than infrared wave? Infrared gas a greater frequency so it should penetrate more and thus cook faster. So I'm not so clear about this.

Thanks for the help

This is not so in general. It may be true for some domain of frequency and for some materials but definitely not true in general.
For example, radio waves penetrate easily wooden walls whereas light usually don't.
