Blackbody Radiation and Wien's Law

This physics video tutorial provides a basic introduction into blackbody radiation and wien's law. Wien's law describes the relationship between the absolute Kelvin temperature of a heated material and the peak intensity wavelength of electromagnetic radiation emitted by a blackbody object.

one thing i love about the organic chemistry tutor is that he doesn't assume we already know things. like i always forget my exponent laws but the organic chem tutor always has my back

[@Damiii9]

i wish our teachers made sure that too

[@azzanporter386]

When I tell you he's teaching content better than my Modern Physics professor this man is cooking

[@eshmaelashiqui1786]

Dude your older lessons made me improve on my academics, simple and precise. Love your lessons. Keep it up man. 👌🙏

[@inidu179]

Same bro!!!

Planck's approach was to analyze the entropy of blackbody radiation as a function of energy. To make both high-frequency and low-frequency data consistent with the Second Law of Thermodynamics, he included an additional "guess" term proportional to the frequency. Planck's application of Boltzmann's Statistical Mechanics led to his conclusion that the material of the walls emit and absorb radiation in discrete quanta. A paper titled "Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler (7/25/08) gives a nice discussion.

Your videos really helped me in applied mathematics, Modern physics and applied chemistry.

[@deborahfanny3531]

Your videos are amazing. I didnt understand this concept at all and then thus one video just helped me so much......thank for your teachings

[@crt5866]

this man is just pumping out the content!

[@user-gl6br9cy7w]

You are the Beast....best explanation than my Dr

[@modernrecipes]

super super super fun, im just learning atm in my spare time and this was so fun calculating our own star i came out with 5800. thanks a lot!

[@mamudouconateh8308]

You're so amazingggggghhh🎉🎉 🎉🎉 I can conclude that this video has solved 99.9% of my problem 😢❤

[@ΚωνσταντίνοςΛαζαρίδης-ξ9ι]

Rumours say that there is a university topic he hasn't a video for

About the quantum of light 1- In the 19th century, much attention was paid to the study of the thermal properties of various objects. The idealized model that was considered was the Black Body. (Max von Laue called the black body the “Kirchhoff vacuum.” It was also called the “ultraviolet catastrophe”; the first signs of the “vacuum catastrophe”) 2- In 1900, Max Planck solved the “black body” problem by discovering the “quantum of action of light - h”. Particle (h) is not a hot particle emitted by stars. Particle (h) came from the vacuum, from the cosmic vacuum. 3- Einstein's second postulate states: In a vacuum, light propagates at a constant speed (c), which does not depend on the speed and radiation of the source or observer. 4. According to SRT, a quantum of light is not a solid particle. 5- According to quantum physics, a quantum of light has its own internal “spin” (linear or angular). 6- Light is an independent and free quantum particle. Its movement does not depend on the speed of the source or the observer. The actions of light do not depend on the opinions of physicists. # "All these fifty years of conscious brooding have brought me no nearer to the answer to the question "What are light quanta?". Nowadays every Tom, Dick, and Harry thinks he knows it, but he is mistaken." /Albert Einstein/

Im in an ASU online Astronomy class and we arent really being taught. I am having trouble with finding the factor of energy decrease if a star decreases temp. In particular, Star C has a temperature of 9,613 K. If the temperature of Star C decreases by a factor of 4.9 by what factor will the energy decrease? DO you have a video explaining this? Im trying to get help from chatGPT but it gives me mixed answers almost like its trying to please me or something.

[@user-gl6br9cy7w]

You are genius i wish i can have a conversation with you in person....

[@salmam7654]

Can you please make a video about raylength Jean law

[@hainguyenthithanh7686]

You can explain me that The temperture is of heated metal or source of temperature ?

[@hashiyakamarudheen4239]

Increase the energy....it will emit shorter wavelength with high freq

[@Beserious]

Woah I’ve never been this early before

[@StreamerBTW99]

Same

[@safakhaldi6750]

Thank you. I love you!

[@JohnHDiscs]

I'm so early... Btw, your videos helped a lot in algebra 1

[@As-iy2ki]

Are metres used for wavelength in Wien's Law or nanometre if the question doesn't tell what units to give e.g. nano, pico or metre?

[@abbigamer3864]

Always convert to meters when you are calculating. However, you can covert your meter-answer in nanometers

[@pabloa2228]

Didn’t this lead to the ultraviolet catastrophe?

[@c.h.s1001]

yup

[@jithinajith4295]

Which textbook is this?

[@jithinajith4295]

Which textbook questions?

[@TheCosmicGuy0111]

Nice

[@IITJEEADVANCEXD]

needed

[@deepdays9068]

I don’t Understand but ok

[@willieblessings]

5000k?

[@lovelyrukky]

I'm also wondering

[@manep]

he never replies 💔

[@nadamoner9765]

I wish all videos was free😔
