Fossil fuels are hydrocarbon-containing materials that were formed from the remains of ancient plants and animals. They are found in the Earth’s crust and are a source of energy for many human activities. Fossil fuels include coal, oil, and natural gas, and are used to produce electricity, fuel cars, and heat buildings. Burning fossil fuels …
Combustion of fuel is the chemical process in which fuel reacts with oxygen in the presence of heat to produce energy in the form of light and heat. The process is also known as burning. Common fuels used in combustion reactions include coal, natural gas, oil, and wood.
Light pollution is the excessive use of artificial light that interferes with natural cycles and patterns of light and dark. It is caused by the overuse of energy-inefficient lighting, such as streetlights and security lights, that scatter light into the night sky, making it difficult to see stars and other forms of natural light. Light …
The Tyndall effect is a phenomenon in which light scatters when passing through a colloidal solution. This scattering causes the solution to appear cloudy or hazy, and the color of the solution is dependent on the size of the particles and the wavelength of the light. The Tyndall effect is named after the British physicist …
When light reaches the observer after traveling long distance through atomosphere ,which colour reaches his eye The colour that reaches the observer’s eye is usually red, due to a phenomenon called atmospheric scattering. As light passes through the atmosphere, the air molecules scatter the blue and violet light more than the red, so the blue …
Scattering is the process of light being deflected in different directions when it comes into contact with particles or molecules in a medium, such as dust, gas, or water. Wavelength is a measure of the distance between successive wave crests of a periodic wave, such as those of visible light or sound. Wavelengths are typically …
Scattering of light is the process by which light interacts with a material or object and is diverted in many directions. It is an important physical phenomenon that affects the way light travels and is a fundamental part of optics. Scattering can occur when light interacts with particles in the air, such as dust, pollen, …
Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina. This has been used in motion pictures and animation since the late 1800s. Persistence of vision is the reason why fast-moving objects appear as continuous motion and why …
When it comes to colour combinations, it is important to consider factors such as contrast, balance, and harmony. For example, a bold, bright colour can be balanced with a neutral or muted shade. Alternatively, a monochromatic colour scheme can be used to create a calming atmosphere. For a modern look, consider pairing bright and vibrant …

Primary Colors: Primary colors are the three pigment colors that cannot be mixed or formed by any combination of other colors. They are red, yellow, and blue. Secondary Colors: Secondary colors are the three colors formed by mixing the primary colors together. They are orange, green, and purple.
