When light waves travel from air through a solid, they undergo several interactions with the solid material, resulting in various phenomena such as absorption, reflection, refraction, and scattering.
1. Absorption: Some of the light energy is absorbed by the solid material, causing the atoms or molecules within the material to vibrate and gain energy.
2. Reflection: A portion of the incident light is reflected back at the surface of the solid. This reflection occurs due to the different indices of refraction between air and the solid material.
3. Refraction: The remaining light that is not reflected undergoes refraction, which is the bending of the light wave as it enters the solid material. This bending occurs because the speed of light is different in air compared to the solid due to the difference in their optical properties.
4. Scattering: When light waves encounter impurities, defects, or microscopic irregularities on the surface or within the solid material, they can be scattered in different directions. This scattering can cause the light to deviate from its original path.
The extent to which these interactions take place depends on various factors such as the properties of the solid material (e.g., its density, composition, and crystal structure), the wavelength of the light, and the angle at which the light wave strikes the surface of the solid.

will the lightwaves slow down in the medium and bend?
Yes, when light waves travel from air through a solid, they will slow down and bend. This phenomenon is known as refraction. Refraction occurs because the speed of light is different in air compared to the solid material. As light enters the solid, it experiences a change in its velocity as it interacts with the atoms or molecules of the material. This change in velocity causes the light waves to bend or change direction.
The extent of bending or refraction depends on the angle at which the light wave enters the solid (angle of incidence) and the optical properties of the solid material, particularly its refractive index. The refractive index is a measure of how much the material can slow down or speed up light.
If the light wave enters the solid at an angle (not perpendicular to the surface), it will also undergo a change in direction. This change in direction is known as the angle of refraction and obeys Snell's law, which relates the angle of incidence and the angle of refraction to the refractive indices of the two media.
Overall, when light waves travel from air through a solid, they will slow down, change direction, and experience refraction due to the differences in the speed of light between the two media.
