finaaly after surfing the web for these topics for 5 hours i got something really very helpful......and i would like to give 5 stars to ur explanation.......
aap suggestion dene ko bool rhy hy me tb bool rha hu so koi baat ka bura mt manna Aapne acha samjhaya jb aap steradian smja rhy hy thy tb aapne jayda letters ko ik saath likh diya tha usko thoda avoid kijey ik time me bs 3 ya char letter hi likhiy thoda headings ka use kijey and last me sabhi quantity ko normal page pr likh kr ya digital page pr likh kr sabhi quantity ko ek saath likh dijey aur screenshort lene ko boliy jissey bachy jayda relate karenge baaki aap shi me passionate hy kal mera paper hy ueet ka toh bhut smajh aaya so thanks sir🎉
Excellent way of explaining... Thank you so much.. I have been struggling with this topic since so long.. And now, I can explain it to anybody. Hats off👍👍
Always Remember Students👉: Luminous Intensity stays constant for a particular light source & Illumination Varies with Surface Area( Where Flux Falls). Bigger The area, Lower the Illumination & vice versa. Also at 9:25 unit of 4pi is 'Steradian' , & not 'meter sq.' , which is a big-big Mistake There...
I get everything in your video. Thanks for this video as this topic is so confusing. One thing which I don’t understand here. When the object is properly vertical then its on 90 degree and when it is becoming horizontal its is approaching towards 0 according to protector then why u explained that angle is increasing though it was approaching to 0 from 90 Plss clr the doubt sir
Thank you sir itna clear batane ke liye bahut confusion tha🙏🙏🙏.... Ekk sawal aur tha lux meter se lumen/per feet square nikalne ke liye Lux meter ko uss light source se kitne distance me rakhte hai?.....
Mukesh apke Question k do part hain: part 1 - Lumen /feet me ans chahiy. To y to LuxMtr me setting hota hai, use feet pr switch kar do (Button se), Ans Lumen per feet me ans aa jayga. Part 2 - kitne Distance pr rakhen? - to iska jwab hai ki 'Here Distance doesn't matters' 😄😄😄 ap pass me rakhoge Illumination jyada hoga, dur lejaoge Illumination kam hojayga. Lumen per feet to unit hai, iska Distance se koi lena dena nhi h. Hope ki apka doubt clear ho gya hoga.
Mean horizontal candle power: (M.H.C.P) It is defined as the mean(average) of candle powers(Luminous Intensity)in all directions in the horizontal plane containing the source of light.
Look Anjan : first of all it is very similar to MSCP (explained here in this Video) just Inseated of 4pi in Denominator, there will be the area of that Horizontal Plane, and rest will be same.
As I have Only Definition yet for MHCP, I Assume that, as per MSCP & MHSCP, formula for MHCP will be : MHCP= Total Flux (of a flat light source)/Total Surface Area( Flux Emitting Area)(unit may be ' Lumen / cmsq. )
Bhai sab thik hai lekin luminous intensity kaise change hogi.....kyun ki ek hi solid ka total emitting flux bhi constant hai..aur....solid angle bhi change nehi hogi....isliye luminous intensity har area k illumination mein same hi rahegi
I think this Question is from Law of Illumination Part: You are Right, Luminous Intensity is a Constant thing here for a particular source, But Illumination Changes according to Distance between Source and Surface
Always Remember Luminous Intensity Varies with SolidAngle & Illumination Varies with Surface Area( Where Flux Falls). Bigger The area, Lower the Illumination & vice versa.
Hello Ankit! Actually I had started my coaching few times and I am busy with it right now but very soon I will start uploading videos on various topics which will fulfill your needs and clear your doubts regarding that respected to topic
