GCSE Physics - Microwaves and Infrared #66

This video covers:
- How microwaves are used to heat food
- How microwaves are used in satellite communication
- The idea that hotter objects emit more infrared radiation
- How we use infrared radiation to cook things

I just want to say that I had a test in one week and I did zero revision and I didn’t know how to but then I saw this guys channel and I got full marks on the test, I genuinely want to say that this guy puts so much effort in his videos and these really help.

[cazoxv]

You are saving my GCSE's right now! Thank you so much!

[Jek_nintendo]

Glad I have notations on ! Got an A* in physics today aswell 😂

[HiMeee]

Someone remind me to come back so i can let u guys know my physics results when i get them 😭😭 goodluck to everyone doing physics tmr!! Last paper guys, do ur best and don't give up 👍

This video is awesome, I am only in Year 8 but this explanation has helped me a load. Thank you.

ok, this is super helpful and all.. but who cooks their apple 🍎

[creativeaaditya]

3:17, what kind of a psychopath heats an apple!

[bengoody]

Regarding Microwaves, are the smaller amplitude microwaves the ones that are absorbed by water and the larger amplitude waves the ones used for communication?

[nicholasmitchiner]

just wondering. Will you do a series on the astronomy GSCE content or not?

[abdmations]

I understood everything except why would anyone put there apple in a microwave

[AmenaAhson]

Now I can pass my test which is tomorrow thanks a lot sir.

[Noor-ibhf]

Hello! will you be making a level physics content too, for example a level physics qs by topic, just like you've done for biology and chem a level? thanks!

Great channel. But all satellite TV antennas are stationed on the ground just like radio and cellphone towers. In fact a lot of times radio, cellphone, and satellite tv antennas can be seen sharing the same physical tower structure, just placed at different heights and directions to prevent interference. :)

[realityaspirations]

So basically microwaves must be causing infrared radiation to be produced from the food. as heat is infrared

[ImBobtheHampter]

I like all the videos I watch, subscribe and also share with my friends

[Wojbest_YT]

@Cognitoedu 2:23 could you confirm no one got burnt in the production of this video😂

[EldanaGirma-tmzp]

Why do u use "by" why don't u say absorb a water molecules

[salmaazzzam]

in AQA should we know this for the foundation paper or only the uses of each wave

[josephdurston]

I got a A** cos I'm such a freaking smart boy.
