1. If reflected/refracted rays never meet, the image is virtual because the rays only appear to meet when extended backward. This happens in plane & convex mirrors and in diverging lenses, or in converging lenses when the object is inside F.
2a. Refraction is the bending of light as it changes speed moving between media. 2b. Rules: (1) Low→high density = toward normal. (2) High→low density = away from normal. 2c. Higher optical density = higher refractive index. 2d. Symbol = n.

1. Essay on National Unity
National unity is the foundation of peace, progress, and stability in any nation. It is the feeling of togetherness, harmony, and mutual understanding among people belonging to different castes, religions, languages, and regions. In a country like Nepal, where people follow diverse traditions and lifestyles, national unity becomes even more important. Unity helps citizens work together for common goals, protects the nation’s identity, and strengthens...
1. Transmission Media
Transmission media refers to the physical or wireless pathways through which data travels from one device to another in a network. It plays a crucial role in determining the speed, quality, and reliability of communication. Transmission media is broadly classified into guided and unguided media. Guided media includes cables like twisted pair, coaxial cable, and optical fiber, where signals travel through a fixed physical path. Optical fiber offers the highest bandwidth and

Primary Network Topologies
Network Topologies describe the physical or logical arrangement of nodes (devices) and their connections within a network. They define how devices are interconnected and communicate with each other.
Factors affecting Network Topologies:
Scalability: The ability to expand the network easily influences the choice of topology. For example, star and tree topologies are more scalable because additional devices can be added without disrupting the existing network. In contrast,
A fluid is a substance that continually deforms (flows) under an applied shear stress.
TYPES OF FLUIDS
Ideal fluid A fluid is said to be ideal when it cannot be compressed and the viscosity doesn't fall in the category of an ideal fluid. It is an imaginary fluid which doesn't exist in reality. Real fluid All the fluids are real as all the fluid possess viscosity. Newtonian fluid When the fluid obeys Newton's law of viscosity, it is known as a Newtonian fluid. Non-Newtonian fluid When the fluid doesn'
#ELISA: Antigen is detected with a primary antibody and a secondary enzyme-linked antibody. Step: Antigen, wash/ primary, wash/ secondary, wash/ add substrate(HRP), measure signal(color).#Plasmid miniprep: purify plasmid from bacteria.

Even if you aren't a big eggplant fan, you might enjoy this despite yourself. Broiled eggplant has a crunchy and meaty texture, and the tahini dressing makes the salad rich and creamy.
1 medium eggplant, sliced into circles
1 tbsp lemon juice
1 tbsp tahini sprinkle of chili flakes (optional) fresh dill, finely chopped (optional) salt and pepper
Turn on your oven's broiler. Arrange the slices of eggplant on a baking sheet, then place them under the broiler for about 3 minutes. Watch them carefully.
