Like when you are driving down the road on a hot day and up ahead in the road it looks wet, but when you get there it's not. That's a Mirage or an optical illusion.An example of an optical illusion due to refraction is the formation of rainbow caused by action of water droplets as prism.

The purpose of optical media is to store and retrieve digital data using laser technology. Common types include CDs, DVDs, and Blu-ray discs, which are used for various applications such as music, video, software distribution, and data backup. Optical media offers advantages like portability, durability, and relatively low cost, making it a popular choice for both personal and commercial use. Additionally, it allows for large amounts of data to be stored in a compact format.
Axonometric optical drawings primarily include three types: isometric, dimetric, and trimetric projections. In isometric projection, the angles between the axes are all equal, typically at 120 degrees, leading to a uniform scale along all three axes. Dimetric projection features two axes at equal angles, resulting in two scales, while the third axis has a different scale. Trimetric projection allows for all three axes to have different angles and scales, providing the most flexibility and detail in representation.
There are three types of Pictorial Drawing: Isometric Drawing Perspective Drawing Oblique Drawing
False, They can use optical storage discs.
Some examples of optical disks include CDs (Compact Discs), DVDs (Digital Versatile Discs), and Blu-ray discs. These disks are used for storing and playing back various types of digital data such as music, videos, and software.

An optical drive is an input and output device. It reads data from optical discs like CDs and DVDs (input) and writes data to these discs (output).
Three common types of secondary storage are hard disk drives (HDDs), solid-state drives (SSDs), and optical discs (such as CDs and DVDs). HDDs use magnetic storage to read and write data, while SSDs use flash memory for faster access and improved durability. Optical discs store data using laser technology and are often used for media distribution and backup. Each type has its own advantages and is suited for different storage needs.

A optical drive is essentially what you put CD's DVD's and install discs into.
The three main types of optical drives are CD drives, DVD drives, and Blu-ray drives. CD drives read and write CDs, which can store up to 700 MB of data. DVD drives handle DVDs, with a capacity of 4.7 GB for single-layer disks and 8.5 GB for dual-layer disks. Blu-ray drives support high-definition content and can store up to 25 GB on single-layer discs and 50 GB on dual-layer discs.
There are primarily three types of friction discs: organic, ceramic, and metallic. Organic discs are made from a composite material that includes materials like rubber and kevlar. Ceramic discs are made from a mixture of ceramic fibers and copper. Metallic discs are made from a combination of steel and other metals.
