frequency change take place
A light wave would not be able to pass through a opaque medium, such as a solid wall or a thick sheet of metal, that does not allow any light to pass through.
Waves, such as sound or light, can pass through a medium. The medium can be solid, liquid, or gas, and the particles in the medium vibrate or oscillate as the wave passes through. Energy and information can also pass through a medium in the form of waves.
The light will pass straight through the glass block if shone perpendicularly, without getting refracted or bent due to the change in medium.
An optically opaque material.
When light bends, it is passing through a medium with a different optical density, such as air to water or glass. This change in medium causes the speed of light to change, resulting in refraction or bending of the light rays.

Refractive index is the ratio of speeds.
When light bends, it is passing through a medium with a different optical density, such as air to water or glass. This change in medium causes the speed of light to change, resulting in refraction or bending of the light rays.
Light can pass through water because it is a transparent medium, meaning it allows light to travel through it relatively unobstructed. Water molecules do not absorb visible light, so it can pass through the water easily.
Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.
Yes, light is able to pass through a suspension. A suspension is a heterogeneous mixture where particles are temporarily dispersed in a medium, but they are not dissolved. Light can interact with the particles in the suspension, causing it to scatter or be absorbed to some extent, but some of the light can still pass through.
The speed of light in a material medium is slower than the speed of light in a vacuum. This is a consequence of the electromagnetic wave interacting with the atoms and molecules in the medium, a process merits its own question.Of course, this assumes the medium is transparent for the wavelength of light travelling through it.Light waves slow down when they pass through a medium, eg glass or water
When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.
