Max Planck's Contributions to Physics. How does it apply to everyday life?

AI Thread Summary
Max Planck's contributions to physics, particularly in quantum theory and black body radiation, have significant implications for everyday life. Quantum theory, initiated by Planck, is foundational for modern technologies such as semiconductors, diodes, transistors, and microchips. Black body radiation is exemplified by the Earth and sun, affecting how we perceive light and heat. Understanding these concepts is essential for grasping advancements in various electronic devices. Planck's work continues to influence both theoretical and practical applications in physics today.

I have a presentation to do in Physics tomorrow on Max Planck.

How does quantum theory and black body radiation apply to everyday life?

I've looked everywhere for it but can't find anything! If someone could just point me into the direction of a website or something I would be very happy.

I've been stressing over this project for the past week.

I know that perfect examples of black body radiation is the Earth and sun but is it everyday life? I think it is.
 
Physics news on Phys.org
If the sun were not a BB radiator, and say it radiated only within some small band of wavelengths, how would that affect the way we see things ?

Any devices that involved microscopic manipulations of atoms, molecules, ions, electrons or photons (remember, all EM radiation is made up of photons; not just visible light) are designed using calculations based on quantum theory. Can you think of a few such devices ?

Hint : you don't have to be an 'idiot' to think of this one.
 
are you implying that I'm an idiot?
 
And can you put that in simpler terms for me?

Mind you that I'm a hs junior

I'm sure Gokul didn't mean offending you in any way... :rolleyes:

As for the question itself,'hs junior' means first year of HS...??If so,then what does physics taught in the first year of HS goota do with Max Planck??
Do you know thermodynamics??Max Planck had great contributions to thermodynamics.Do you know quantum theory...??Max Planck founded quantum theory.

Quantum theory began with Planck. Quantum theory led to the understanding of semiconductors... which in turn led to the diode, transistor and microchips...

Of course there are others that contributed to quantum theory along the way.
 
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...
