Light Transmission

Light transmission occurs when light passes through a material such as air, water, glass, or even living tissues. The ability of a material to transmit light is determined by its transparency and refractive index. Transparent materials allow light to pass through with minimal absorption or scattering, while materials with higher refractive indices can bend or slow down the light as it passes through.

Sound Transmission

Sound transmission involves the propagation of mechanical vibrations through a medium such as air, water, or solids. When an object vibrates, it creates sound waves that travel through the medium, causing particles to compress and rarefy. The speed of sound transmission varies depending on the medium's density and elasticity.

Heat Transmission

Heat transmission, also known as thermal conduction, occurs when heat energy moves from a warmer object to a cooler one. This process is governed by the material's thermal conductivity, thickness, and the temperature gradient between the two objects. Materials with high thermal conductivity, such as metals, are efficient heat conductors, while insulating materials like wood or foam have lower thermal conductivity.

Electricity Transmission

Electricity transmission involves the movement of electric charge through conductive materials such as metals or through an electrical circuit. Conductors allow the flow of electrons, enabling the transmission of electrical energy, whereas insulators impede the flow of electrons.
