the speed of light, commonly denoted as "c", is constant no matter which medium it passes through.

When a beam of light passes through a colloidal solution it scatters because of tyndall effect.

The Iris
An aperture is an opening in the centre of your lens through which light passes. The amount of light, which passes through an aperture, is indicated by f/stops or f/numbers. The lower the f/stop the more light that passes through the aperture. Opening up one full f/stop doubles the amount of light entering the camera. F/4 admits twice the light of f5.6. www.goldprints.com
The answer to this microscope question is the stage opening.
Light is scattered as it passes through a prism.
Light passes through the cornea, the aqueous humor, the pupil (which is just an opening in the iris), the lens, and the vitreous humor on its path through the eye to the retina.
refraction and diffraction refraction is when light passes through it bends but diffraction is that light finds an opening to pass through while other waves bounce off
light passes in straight line
