Objects that don't let light pass through them?
Why can't light pass through what? To first contributer, don't say that. Say light cannot pass through solid, opaque objects at times.
Is material transparent if 97 percent of light passes through it?
Technically, transparency is not an on or off (yes or no) thing. There is a degree of transparency and one quantifies this by saying how much (and at what wavelengths) light is transmitted through a medium. Nonetheless, in daily language people say something is transparent when most of the light passes through and a transmission of far lesss than 97 percent falls into that category. Similarly, people use the term opaque when most of the light does not pass through a material but that usually means no detectable light or a very small fraction of light passes through.
What do light rays do as they pass from one transparent material from another?
They refract.When light passes from one transparent medium to another then the light ray refract or we can say it deviate from its straight path.
What colour comes through when a red light passes through a blue filter?
Nothing comes through. A red light emits no blue light, and a blue filter allows only blue light to pass ... that's why when you look at it, you say to yourself "Hey! That filter looks blue. I'll call it a 'blue filter'."
What causes to make ice cream melt faster in glass?
Glass, being that it is transparent, will allow light to pass through it. Since the bowl relative to your ice cream is concave, it will channel all that light in toward your ice cream, causing it to heat up and melt. I say all that light, meaning all the light that is allowed to pass through. In real systems, light moving from 1 medium to another will refracted through and reflected away; both at differing degrees.

What word is it when light can't pass through a block of wood?
You would say that the wood is opaque.

What is it called when light hits a surface that it cannot pass through?
There is no scientific term for what happens when light hits an opaque object I'm afraid to say.
Permeability refers to?
Permeability is a word used to describe a property of a certain material. It describes whether it will allow another substance such as water to pass through it. To use it in example, one could say 'This cloth is all wet, so it must be permeable'

When unpolarized light is polarized what happens to light waves that exist at say 45 degrees to vertical?
Asumming the polariser is vertical, then 100% of vertically polarised light passes through it and 0% horizontal light passes through it. Simple so far. For 45 degree light it gets weired. Each photon of light has a 50:50 chance of making it through. It is impossible to tell if a particlular photon will or will not pass through. it is totally random. If it does pass through however it will change its polarisation to vertical! So a scientist would measure a beam of vertically poloarised light at 50% intensity.
What happens when light passes through something?
The velocity of light is greatest when travelling through a vacuum. When travelling through something else, a glass material say, then its velocity is slower. The refractive index is the ratio of the speed of light in a vacuum to the speed of light in that substance. For example light travels in a vacuum about 1.3 times as fast as in water, so we say water has a refractive index of 1.3. And it is likely that the velocity in the glass will be different at different wavelengths of light.

Does light travel easier through a convex lens or a concave lens?
The "ease" with which light travels through a lens has to do with the material the lens is made of. If a concave and convex lens are both made of the same material, say, silicon glass, then the light behaves in an identical way within both lenses. What happens on the front and back sides of the surface of the lens is a different story. This is because the light will be reflected and refracted differently by the different lenses because of their shape. But the light behaves the same way within both lenses as it is passing through.
