The fine dust sensor uses SHARP’s GP2Y1014AU0F. You can use anything compatible. Micro:bit only works with v2.00 or later products. Please use the Chrome browser if possible. It may not work in the in-app browser of social media (e.g. Facebook). … more
A solid metal can be made by grouping several hot gaseous (monatomic) metals together. What is the difference between emission spectra in the gas (monatomic) and solid state? The simulation above is a simple example and is not representative of … more
A cathode ray tube (CRT) is a device that produces cathode rays (a stream of electrons). The inside of the tube is evacuated or filled with a noble gas. When a high voltage is applied to the cathode ray tube, … more
Let’s assume there is a light source in the middle of the train and sensors on both sides to detect the light. From the point of view of an observer inside the train, the two light sensors are the same … more
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and gravity \(g\) act in … more
You can measure the voltages between 0 and 16.5V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage the micro:bit. If the … more
Oersted’s experiment Oersted, a Danish physicist, accidentally discovered the occurrence of a magnetic field around a current-carrying wire. Oersted said that he was surprised to see the compass’s magnetic needle placed next to the wire rotate while experiment to show … more
