Light waves and mechanical waves differ in their propagation and behavior. Light waves are electromagnetic waves that can travel through a vacuum, while mechanical waves require a medium, such as air or water, to propagate. Light waves also travel at the speed of light, while mechanical waves travel at varying speeds depending on the medium. Additionally, light waves exhibit properties such as interference and diffraction, which are not typically seen in mechanical waves.
Rectilinear propagation of light means that light travels in straight lines in a uniform medium, unless it encounters a change in medium or interacts with matter. This concept is a fundamental property of light behavior and is described by the laws of geometrical optics.
Polarization by scattering affects the propagation of light in different mediums by causing the light waves to align in a specific direction. This can result in changes to the intensity and color of the light as it travels through the medium.
Transverse waves can be both mechanical and electromagnetic. In a mechanical transverse wave, the disturbance of the medium is perpendicular to the direction of wave propagation (e.g. waves on a string). In an electromagnetic transverse wave, the oscillations of electric and magnetic fields are perpendicular to the direction of wave propagation (e.g. light and radio waves).
The propagation direction of light in a vacuum is straight and constant.
The direction of polarization of light is perpendicular to the direction of light propagation.

Sound waves are longitudinal in nature, and they require a medium for propagation.
The direction of polarization of light is perpendicular to the direction of light propagation.
Light typically travels in a straight line, a phenomenon known as rectilinear propagation. This is due to light's wave-like behavior where it travels in a straight line until it encounters a medium with a different optical density, causing it to bend or change direction. This bending of light is described by the laws of reflection and refraction.
The group refractive index is important in optical materials because it determines how fast light travels through the material as a group. It affects the propagation of light by influencing the speed and direction of light waves as they pass through the material, which can impact the overall behavior of light in that medium.
It is different because sound vibrates and light reflects
Different is the speed of propagation. Scroll down to related links and look at "Acoustic or sound waves in air - Radio and light waves in a vacuum".
The relationship between the wave phase and the propagation of light in different mediums is that the phase of a light wave changes as it moves from one medium to another. This change in phase is due to the difference in the speed of light in each medium, which causes the wavelength of the light wave to either stretch or compress. This phenomenon is known as refraction, and it affects how light travels and interacts with different materials.
Light slows down in a medium because it interacts with the atoms and molecules in that medium, causing it to be absorbed and re-emitted. This phenomenon affects the propagation of light through different materials by changing its speed and direction, leading to phenomena like refraction and dispersion.
