Why Do Metals Block Electromagnetic Waves?

AI Thread Summary
Metals block electromagnetic waves primarily due to their free electrons, which absorb and reflect the waves rather than allowing them to penetrate. This property differentiates metals from other materials, which may allow for some level of transmission. The discussion also touches on the relationship between the sun's emission of electromagnetic waves and human visual sensitivity, suggesting an evolutionary adaptation to the environment. The participants express curiosity about these concepts, indicating an interest in understanding the science behind them. Overall, the conversation highlights the interplay between materials and electromagnetic wave behavior, alongside human evolutionary biology.

-Why do electromagnetic waves not readily penetrate metals?

Also a question occurred in class, and they asked

-"The sun emits most of its electromagnetic wave energy in the visible region of the spectrum with the peak in the yellow-green. Our eyes are sensitive to the same range, with peak sensitivity in the yellow-green. Is this a coincidence?"

I think that question was a homework question, but I could not find the answer.

Have you learned what makes metals different than other materials?

For your 2nd question, given that science says we evolved and adapted to our enviornment, what do you think the answer is?

I got the answer thanks :D

The second kind of caught me by surprise, i didn't really expect an answer like that haha.

Heh, I hope I helped. I wasn't trying to be sarcastic or anything, I was really asking what you thought lol.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
