A concave mirror is a spherical mirror in which the reflecting surface and the center of curvature fall on the same side of the mirror. Concave mirrors show different type of images, depending on the distance between the mirror and the object reflected. This type of mirrors are used quite frequently in day-to-day life. Examples … Read more
Crows and ravens belong in the Corvid family (which includes jays, nutcrackers and magpies) and are considered to be among the most adaptable and intelligent birds. Crows and ravens can appear to be very similar, making it a challenge for someone to tell the difference between the two birds. Both birds are completely black and … Read more
Chemical Adsorption also known as chemisorptions is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate whereas Physical adsorption is a kind of adsorption which attaches the target substance on a chip as a result of hydrogen bonding, van der waals forces, electrostatic forces and hydrophobic interactions. Physical adsorption … Read more
In the fast-paced digital age, the television industry has undergone a transformative revolution, offering consumers a wide range of options that promise to redefine their entertainment experience.

Television (the electronic delivery of moving images and sound from a source to a receiver), is currently delivered in a variety of ways: “over the air” by terrestrial radio waves (traditional broadcast TV); along coaxial cables (cable TV); reflected off of satellites held in geostationary Earth orbit (direct broadcast satellite, or DBS, TV); streamed through the Internet; and … Read more
Flames burn by combining their own carbon molecules with oxygen molecules in the air to form carbon dioxide; in this regard heat flames are classified as either luminous or non-luminous flames. The terms “luminous” and “non-luminous” refer to objects based on their ability to emit light. Luminous flames do not get enough oxygen to turn … Read more
Communication is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols and semiotic rules.

Both Acrania and Craniata belong to the phylum Chordata. Acrania are primitive chordates that lack a cranium and belong to the phylum Chordata. Craniata are higher chordates that possess a cranium and belong to the phylum Chordata. Let’s talk in details about the two. What is Acrania? Acrania is refer to a group of primitive, jawless fish … Read more
What is Euclidean Geometry? Euclidean geometry is the study of shapes and figures based on the principles given by the ancient Greek mathematician Euclid in his work “Elements.” It is the branch of geometry that deals with flat shapes and surfaces, assuming that space is continuous and follows the rules of classical geometry. Euclidean geometry … Read more
CMOS stands for complementary metal-oxide-semiconductor, and it uses pairs of transistors to create logic gates. TTL stands for transistor-transistor logic, and it uses multiple transistors to create logic gates. Lets talk more about them. What is complementary metal-oxide-semiconductor (CMOS)? Complementary Metal-Oxide-Semiconductor (CMOS) is a type of integrated circuit technology used in constructing digital logic circuits. … Read more
