We have learned that refraction occurs as light passes across the boundary between two media. Refraction is merely one of several possible boundary behaviors by which a light wave could behave when it encounters a new medium or an obstacle in its path. The transmission of light across a boundary between two media is accompanied by a change in both the speed and wavelength of the wave. The light wave not only changes directions at the boundary, it also speeds up or slows down and transforms into a wave with a larger or a shorter wavelength. The only time that a wave can be transmitted across a boundary, change its speed, and still not refract is when the light wave approaches the boundary in a direction that is perpendicular to it. As long as the light wave changes speed and approaches the boundary at an angle, refraction is observed.
Refraction
The amount of light that is directed from the bottom of an optical microscope through a specimen can be increased by using a stronger bulb or light source. A potentiometer can be used to dim or increase the strength of the light source.
Meteor is the term used to describe the streak of light (also called a shooting star) that passes through the atmosphere. The light is caused when a meteroid hits the atmosphere and burns up.
Its called atomic spectrum

Because a window, although made of glass is NOT a prism...The glass MUST be a prism _____________________________________________________________________ A rainbow forms when light passes through rain droplets. Try getting your hose and an attachment and make a mist to see. ____________________________________________________________________
Marginal rays are the light that passes through an optical system that is away from the optical axis.
When it passes through optical centre.
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
It is called 'polarized light' .
A material through which nearly all light passes is called a transparent material.
When light passes through an object, we say it is transmitted. Transparent objects transmit a lot of light. basically it is called shadow
refracted light
transparent
transparent, or translucent
Nothing. It continues to travel in a straight line.
They separate light into the light spectrum. If a beam of light shines through a prism, a rainbow of color will show out through the opposite side.
When light changes direction as it passes through a boundary.
