printers and ligth

2. medium is a substance through which light travels. It can be solid, liquid, or gas. Different media affect the speed and direction of light differently, which is why refraction occurs.
3. Printers: Ideal for high-quality color prints, such as photos.
4. Uses multiple ink cartridges (cyan, magenta, yellow, black) for full-color prints.
8. Printers: Best for high-speed, high-volume printing. Use toner instead of ink.
9. Body transparent body allows light to pass through it with little to no obstruction, so you can see through it clearly. Examples include clear glass and clean water.
10. Wired network connection for office settings.
12. Matrix Printers: Impact printers that use a matrix of small dots to create characters. Used in specialized applications.
14. Body translucent body allows some light to pass through, but it scatters the light in different directions, making it difficult to see through clearly. Examples include frosted glass and wax paper.
15. Prints only in black and white.
16. Printers (MFPs): Combine printing, scanning, copying, and sometimes faxing.
17. Most common, direct connection to a computer.

1. Wireless printing from multiple devices.
5. occurs when light rays bounce off a surface. This is why you see your image in a mirror. The angle at which light hits a surface is equal to the angle at which it reflects off that surface.
6. Wireless connection for close-range printing.
7. happens when light passes from one medium to another and changes direction. This is why a straw looks bent when it's partially submerged in water. It's the bending of light due to a change in its speed.
9. Printers: Often used for receipts and labels. Use heat to transfer ink.
11. (Near Field Communication): Allows quick connections for mobile printing.
13. Body opaque body does not allow any light to pass through it. Instead, it absorbs or reflects all the light. Examples include wood, metal, and stone.
