HOW TO MAKE A LIGHT UP STAR CEILING

How to make a light splitter using CDs

To create a CD spectroscope, start by cutting a narrow slit in a cardboard box to control light entry. Position the box so that light hits the shiny side of a CD at a shallow angle, causing diffraction. Often used to look at stars or gemstones, the resultant spectrum enables the viewer to determine the makeup of the. With a simple tool called a spectroscope, astronomers can break light apart to study stars, planets, and galaxies—even from millions of light-years away! In this activity, you'll build your own spectroscope and discover the rainbow hidden inside everyday light sources.

How to make a 90° right-angle cable tray

Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. By applying the following formula you can quickly find the size of cut out section that you need to cut out of the side of. Elbow joint RVS is pushed inside the cable tray and attached with the included screw set. Construction of a flat 90° bend (A) The amount of tray lip to be removed is equal to 2, 3/4 the width of the tray, half of this measurement will be removed on either side of the centre line. Great if you are new or just forgot how to do it, this easy to follow guide makes it so simple.

How to connect the exposed light wire junction box

Inside the junction box, connect the black wire from the circuit to the black wire of the light switch with a wire nut. It involves connecting the wires from different lighting fixtures to a centralized junction box, which then connects to the main electrical supply. Junction box wiring refers to the process of making electrical connections within an enclosure designed to protect these connections from the environment and accidental contact.
