ELi5: Why do 5GHz wifi signals have trouble passing through walls compared to 2.4GHz wifi signals even though higher frequency means more energy and thus more penetration power?

Question

Please make me understand this as I’ve been trying to figure it out and it’s been bugging me so much!!

Answer 1

When talking about radio waves, the lower the frequency, the higher the range. That is why 2.4 ghz has higher range but 5 ghz has lower range.
