The Photon - A Level Physics

This video introduces and explains the Photon for A Level Physics.

What exactly is a photon? This video shows how we can use the particle model, with individual corpuscles of energy, to explain certain properties of EM radiation. In quantum physics we discover a phenomena called wave-particle duality - this is very important for understanding the photon.

Thanks for watching,

Lewis

I HAVE EXAM IN 4 HOURS AND U JUST SAVED MY GRADE

Using LEGO bricks? Brilliant! Very good quality video!!

[markhardy]

Your videos are always helpful. I appreciate your use of props in your videos. I can't learn well without them.

I am amazed that a photon travelled millions of years just to reach me, I feel blessed

Nice video! Just a note, the RGB thing is about *our perception, * not "the nature of light itself". Adding red, green, and blue into a single stream of light, does *NOT* repeat *NOT* 'make white light', it is simply "how humans see light", so it only looks white *TO US*, but to many other sorts of organisms we may look dimly lit or even unlit under an "RGB White" illumination, whereas a 'natural white' (as our matching of sunlight is called, and as 'color index rating' or 'CRI value' refers to the % accuracy of) has individual photons of the whole range from near infrared to near ultraviolet. To us, the two look indistinguishable, but they are not the same thing.

u have got an inborn talent of explaining well

[rifathossain]

thankyou! that was very neat . i was really confused about how the atomic spectrum worked this cleared things up!

[rizwanaakmalkhan]

please make a video explaining "Band Theory" too..it's newly added in the syllabus for 2016. MUCH appreciated, thanks!

[usefbmf]

So some of the stars we see now are already dead, the more distance the older it is wow, it's actually amazing it u think of it

[legionliberator]

pretty awesome video! this explains a lot!

Question - regarding EMF, which energy source produces the photon, electricity or magnetism?

[ophiolatreia]

Anyone else notice how smooth that pen writes?

[Hfanstar]

ever thought about making a patreon page or similar for donations, means those that want see more can and those that cant afford it are still able to access it, just and idea, great videos though.

[carlybailey]

you taught me more in 4 minutes than my teacher can in 2 hours... 😂

Images could be the vehicle of the quantum photons medium to understand us. As energy is created, vision creates frequency, and a pocket of information is displayed on the watercolor.

[alisterdavid]

0:15 anyone else notice the spelling mistake - QUAUTUM, lol love your videos btw

Photon= Light !" The secret of light " by Dr. Walter Russell...Quote :" In the wave lies the secret of creation " Thanks

I have a question.
If you fire a single photon onto a piece of plastic in space, would different observers at different locations be able to see it's impact?
If so, does the photon split up in billions of different photons, some of which are received by the eyes of the observers?

[Anarchhh]

What exactly is the difference between photons and quanta?

[schmetterling]

And there is another person on the internet who doesn't know what photons are but who is desperate to explain photons to you all. :-)
