False. They were discovered using a light microscope.
True

Any organic substance or sample thin enough to let light through.
False. Light cannot pass through mud, cardboard, dark beer, or concrete. I think there are also some more opaque substances too.
False, mechanical waves need a medium to travel through. Electromagnetic waves, such as visible light, don't.
In general, an aperture is a hole through which light travels. In relation to photography, where the word is most commonly seen, this denotes the size of the hole through which light travels to hit the camera's sensor. Longer exposures need smaller apertures to ensure that the picture is not overexposed, and shorter exposures need a larger aperture to get enough light.
to focus light means to condense the energy of a light beam down to a smaller beam through refraction.
To illuminate what you are looking at or to give enough light to see through something you are looking at.
The duration of False Light is 1.5 hours.
Any organic substance or sample thin enough to let light through.

when its dark your pupils grow because they are trying to look for light for them to see, and when its too light, they get small, trying to minimize the light going through them
