Humne class me alag alag frames per second pe dekha toh 60 fps pe best and 24fps pe worst tha. Still mere paas raw video hai usme clear white hai and bacho ko bhi white dikha lekin ab jab video upload ki toh aisa😲. I guess upload karne ke baad wapus se fps change ho gye🙄. But it is magical🙏
There were some activities given in the ncert textbooks , I always used to think who is going to perform all these activities Finally found a man who performs them 😂 Great teaching sir ❣️❤️🙏🏻
𝗘𝘅𝗽𝗹𝗮𝗻𝗮𝘁𝗶𝗼𝗻 - To see an object the image must be formed on the retina. As soon as the object is removed so the image dissapears,but the brain remembers the image for 1/16 of a second even after object is removed.This eye property is known as persistence of vision. So, when we rotate the Newton's disc very fast, the colours get mixed together and disc appears whitish.
guys lets make cocaine * 1 kilo of coca leaves * 1 gallon of kerosene * 1 gallon of sulfuric acid • 1 gallon of acetone * A large pot * A strainer * A glass baking dish * A spoon A coffee filter * A rubber band 1. Prepare your workspace. Make sure you are working in a well-ventilated area. Cover your work surface with newspaper or plastic. 1. Dry the coca leaves. Spread the coca leaves out on a flat surface and let them dry in the sun for several days. 2. Crush the coca leaves. Once the coca leaves are dry, crush them into afine powder. 3. Mix the coca leaf powder with kerosene. Add the coca leaf powder to a large pot and cover it with kerosene. Stir the mixture until the coca leaf powder is completely dissolved. 5. Add the sulfuric acid to the mixture. Slowly add the sulfuric acid to the kerosene/coca leaf powder mixture. Stir the mixture constantly 1. Let the mixture sit for 24 hours. 2. Filter the mixture through a strainer. Strain the mixture through a strainer lined with a coffee filter. 1. Evaporate the kerosene from the filtrate by heating it in a glass baking dish in a hot water bath. 2. Scrape the cocaine crystals off the bottom of the baking dish. 3. Enjoy your cocaine
This is a newton disc So basically it has seven colour of the rainbow and when you soin it , it will become white in colour It works on the basis of like we see the sunlight , sunlight is made of seven colour Red yellow orange blue green indigo violet so when we see light through a prism it shows these 7 colours. Means when a rainbow is formed the water droplets of rain works as prism and the sunlight passes and it makes a rainbow Thxx
For those who don't know This experiment is called Persistence Of vision. According to this light rays fall on our eyes for the time of 0.625 seconds. If the light is faster than that we will see it in white color. The thing the guy is using to rotate is called the NEWTON'S DISC
The colour in the last is likely white because white colour consist of 7 colors which are VIBGYOR and when all of these 7 colors rotate at high speed their lights again combine and form white color ✨
Sir its Newrons disc i guess because when a rainbow cloured disc is rotated on a *high* speed results to formation of white . This is also related to dispersion because when white light passes through a glass prism results in dispersion of rainbow colour lights please comment sir im a 7 grader and this is taught in physics
@@Uchihha-L fir to direct padh kar bhi Keh sakte hai na.... 9th se se12th ke students imagine to kar hi sakte hai.... Mujhe laga ye 3rd std se 8th ko padhate te hai.... 😂😂😂Itta to mai bhi apne students ko experiments visualise karta hu.... Maine Iss sir ki videos dekhi, aaj tak mai samaj raha tha ki ye primary students ko padhate hai 🤣🤣🤣.. Itna to mai bhi itna baccho bachoo pyar se nahi bulata jitna ye sir bolte hai.... Ye sir jitna visualise kar ke batate hai usse Kai guna humare primary students self study kar bhi lete hai aur samaj bhi lete hai....
Those who dont understand : ye ek activity hoti hai is activity mein seven colours hote hai jinhe spin krke white colour bnta hai isi liye jiske mein same quantity ke seven colour honge aur spin hoga vo white colour bnadega❤
Yeh isliye ho raha hai kyuki sun main bhi rainbow color hote hai but jab woh mix hote hai toh white colour banta hair aur sab kuvh visible hota hai sunlight se.
@@girly_queen Your device display fps may be low. All colors mixed together make white but it must move fast enough to get mixed well. If the camera or display fps is low, the mixing won't be good.
Because When we break a white light through a aide of glass prism it breaks and becomes Seven Colours i.e. VIBGYOR V-Violet I-Indigo B-Blue G-Green Y-Yellow O-Orange R-Red
