White light contains all colors. When white light passes through red glass, for example
(or any red thing that passes light through it), all of the colors except red are removed
(filtered out) so the resulting light only contains the color red.
This is a big part of the reason why that piece of glass comes to be called "red" glass.
The red is absorbed and all the other colours are reflected so it appears red
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.
almost none the vast majority of visible light passes through the atmosphere.
When light passes through a substance near 0 degrees Kelvin, it bends and becomes deformed.
Diffraction.
if the light passes through something that is coloured the light changes colour to the colour that it passed through
violet
white colour composes into seven colour when they passes through spectrum of prism
SPECTRUM
"Opaque" and "transparent" refer to the amount of light that passes through the colour, not the colour itself. "Opaque" is a term used to describe any solid colour that light does not pass through. If you put an opaque colour it over another colour you will not see the colour below through it. "Transparent" is a term used to describe any colour that light passes through in any of many varying degrees. If you paint a transparent colour over another colour, you will be able, to some degree, to see the colour(s) and the ground (paper, canvas, whatever you are painting on) through the top coat.
Red.
Light is scattered as it passes through a prism.
Out of the visible colors, red. The lower the wavelength the less it is dispersed.
light passes in straight line
You see a rainbow in the sky because of the interaction of sunlight with water droplets in the air. When sunlight passes through the water droplets, it is refracted (bent) and dispersed, creating the different colors of the rainbow.
Opaque - light does not pass through. Transparent - all light passes through. Translucent - some light passes through.
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
