GUJ 7- Dos Light have colours? Or it is our perception only. H C Verma talks about this to Gujrat teachers. Addressing Gujarat teachers in a workshop (2018) - 7
00:36 This is exactly how a teacher feels when he's planning to take your mind to the SPECTACULAR PARADISE of PHYSICS. Lots of love and respect sir. Thanks a lot for the video.
Eventough I am biology student 12th cls phy will be end of phy in my life.... But I like phy most... because of some duties and problems I took biology ...one thing which I firmly believe is that my interest of phy will take towards my goal ... Nature mai separately koi subject as phy ,che, bio nhi hai so my knowledge of biology will help me...( HC Verma sir lectures my dreams ..)
Great professor as always. Unfortunately, I understand only English. I am artist and I understand colours and how white light makes colours through prism. That is just it. Hello from Ireland.
White light doesn't consist those seven colours. Its our brain that picks different colours after white light passes through prism. Light is electomagnetic wave only so it can't be colourful. So the colour we see after passing through prism is our mind telling us"look look we see different colours"
This is right sir electromegnetic wave has not any colour but Sir actually the reason of different colour is ours perception power of eyes or that frequency of light or wavelength in that range ???
Then muze batavo sir hame rainbow kyu 7 colour s dikhata he kya o bhi chemical locha hai... Brain ka.... 😊😊😊😊! Kyu ki o to hame sidha sidha hame dikhta hai... And here we are not use any prism...
Vha bhi refraction hota hai with droplets of water present in air same as what a prism do. And we are able to watch only 7 colours sue to our brain system . Its also said that many other animals are able to watch more than 7 colours in even white light .
Respested sir, I wish to have coachings from you but I'll be honest that I do have coachings. But I do not have a mentor to guide me for getting in IIT. So can you be my mentor?
It's because of dispersion when the light goes through the prism it produces diffrent types of em waves and afterwards those diffrent wave produces diffrent sensation in our eyes
If our mind sence the colour then why Red light always visible as red ... Blue as blue...so many And why Only 7 colours. Why not our mind sence more then it at same
Sir, Why do we have seven color when there are only 3 primary colors Red, Green and blue? So does that mean the other colors except these 3 in rainbow are just combiations of these?
A bullet of mass 50g moving with an initial velocity of 100 m/strikes a wooden block and comes to rest after penetrating 2cm .What is the resistive force caused by wooden block? The answer when I searched on Google is 12500N.But sir I think that this answer is not correct as if the the resistive force is equal to the force of bullet it will not penetrate into the wooden block. Sir,Can you please tell me the correct answer.
Nasha jo hota sharaab mein ti naachti bottle Supperrrrrrrrrrrr sir 😍😍🤘😎😎 Hamare jaiso ko aapse hi bharosa hai Warna class ke techer to ye kehkar taal dete hai ki ye teri book meim kahan hai daat uper se lagate hai Bacchey aur majaak banate hai 😔😔 Par aapko dekhkar yekeen hai ki physycs apne concept nahi todti Everything has a logic 😍😍😎😎🤘🤘🤩🤩🥰🥰
@@donotbebiased6987 bhaiya ji Not everything is fundamental Physycs meim bas kuch ginti ke forces hi fundamental hai Warna baki sab Un fundamental cheejo ka complex combination hai Aur us complex combination ko solve kartey kartey fundamental tak ka safar hi hai usko samajhna Par tumko meri baat samajh nahi aayegi Isliye koshish bhi mat karna😂 Aur hc verma sir ko ham itna iseeliye pasand kartey hai ki Ye hamko us fundamental tak diaplace kar dete hai yani shortest easiest way se usko explain kartey hai 🥰🥰🥰🤩🤩🙏🙏😻😻
Sir mera doubt tha ki hmm infinity colour kaise dekh lete hai jaise ke dark pink dark red veryvery light blue yeh sab kaise dekh pata hai or fir Newton ki dispersion theory aise btaye gya hai ki white light mai seven prominent colour hote please explain
Sir, I want to be your security guard because of your free lectures and your present security guard is so occurred because he couldn't understand what you are teaching.
Sir I am in class 10 I have a doubt Can the average speed calculated like (Initial speed + final speed )/2 If yes how,if not why I would be very thankful to you
it can be calculated only if distance vs time graph is linear and in other cases its not calculated like this bcz average speed = total distance/total time taken while not average speed is average of different speeds in other cases as distance travelled at every sec is different
@@harshpawar8882 i already wrote if we u r doing u+v/2 it means u r assuming constant speed over the time but that's not the case everytime Draw graph of distance vs time considering object move 10m/s for 5 sec then calculate average speed by u+v/2 in other case draw a graph for 5 sec but in first 2 sec with 5m/s nd in rest 3 sec with 10m/s and in both case calculate by total distance/total time nd u+v/2
Sir ,I have a question if color are just sensation of our brain creating difference between color of different wavelengths and frequency so, when we r looking at shadow or in any dark place and if we use light beyond visible region what r we looking light or dark?
either its pass from object like gamma rays or reflect back like infrared we can't see any change as we see shadow when we can see rest of visible light coming from all region except that dark region in this we can't see that rest of spectrum now its absorbed reflected or transmit doesn't matter to our eyes
sir, when pass through prism, different wavelengths (colour) bend clearly different, then how is the mixture of light is formed like(grey, magenta) form
The audiences are gujarati teachers and it's a workshop. I wonder how these fellows get teachership at the first place. There response says the other way .😬😬😬😬
If we so able to change the internal circuits of the brain, is it possible that our brain would percept more than 7 Colours? I mean how to reorganize the brain so that our brain can see more than 7 Colours?
Sir ye log teachers hi hai na Fir ye itni aasaan baat kyo nahi bata paa rahe Seedhi baat hai frequency ke karan hoti hai laal ,peeli ,neeli etc. Am i right 😳😐🤨
But sir it is said that we can see red Or any other colour when only the colour is reflected by an object So it is meant that there is the existence of colour before it comes to us So please sir focus on my doubt
ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sB_Y_afxH88.html sir iss video me jo keh rahe he us science ke baare me apka kya mat hai ? please reply kare
We got a good information about light sir but I have a doubt that when light falls on the prism got refracted and we see 7 colours? From where these 7 colours came from?
