It depends on whether the substance is transparent, translucent or opaque. A transparent substance allows nearly all the light through. A translucent substance allows some light through. An opaque substance blocks all the light.
When light passes through a substance near 0 degrees Kelvin, it bends and becomes deformed.
When light passes through one transparent substance to another, it can either be absorbed, reflected, refracted (change in direction), or transmitted (pass through). The behavior of light will depend on the properties of the substances and the angle at which the light strikes the surface.
The light that passes through a substance is called transmitted light. It refers to the portion of incident light that travels through the substance without being absorbed or reflected. Transmitted light can have a different intensity, color, or polarization compared to the incident light.
It happens by the refraction of light.
sh@@ happens
The light refracts or bend .
When light passes into a denser substance, it undergoes refraction - its direction changes because the speed of light is slower in the denser substance. The light ray bends towards the normal (an imaginary line perpendicular to the surface) at the point of entry into the denser substance.
It is transmitted.
it refracts
It is redirected as it passes through a medium
It is redirected as it passes through a medium.
it travels at c (speed of light in a vacuum)
