👋👋 . 🎉. 🎉🎉🎉 This is comprehensive information and in simple understanding way .If any thing gets miss please comment it thank you.🙏 ⚡ What is photoelectric effect? ⚡ The effect of ejection of electrons from the metal surfaces when an amount of frequency hit the metal surfaces greater than its Theshold frequency.🧐 { Theshold Frequency :-The amount of frequency requied to remove the electron from effect of internal forces is known as theshold frequency.} few extra points:- ⚡The photoelectic effect could be most often in the alkali metals and alkali earth metals.[alkali metals are Ia group and alkali earth metals are IIA group in modern periodic table.]⚡ 🤗Frequency is directly proportional to Energy.(so we can assume that amount of frequency as amount of energy applied) 👩🔬Great scientist who involved in its development:-👨🔬 Albert Einstein Albert Einstein was the person who resonablely gave a proper exp...
This is just an 💡💡Idea 😃 Spinning bottle Steps to follow It's a major step to choose a right bottle🍶it might be a plastic bottle . Cut it half and pour some water in it might be half ensure that the cap is fitted very tightly It's a shot introduction:. Inside itself there should be motor arranged with a fan in it.and a small battery to power the motor and a switch to turn on circuit the fan will spin the water in side it and the bottle itself must be spin even with a small torque with being with equilibrium. problems in building it when the motors spinning the water and bottle gets spins up the bottle gets excess for the bottle is accessing the one bottle then get unstable and I get fall immediately. So fill appropriate amount of water in it. This is a diagram showing my idea Spinning bottle The motor should be placed at write place or might be centre of the bottle The cap of plastic bottle should be some what convex not completely only very very small....
