When electricity is passed through a gas, it causes the gas atoms or molecules to become excited and emit light at specific wavelengths. Each gas has a unique set of energy levels, so when electricity is passed through it, the emitted light will reveal the characteristic color associated with that specific gas.
after pupil first light enters aqueous humour or pupil
Light first enters the eye through the cornea, the clear outer covering of the eye that helps to focus light. The cornea then bends the light and directs it through the pupil, the black hole in the center of the colored iris.
The federal government now requires that ceiling fan light kits be limited to a maximum of 190 watts. When the light is first turned on, a small current is passed through the bulbs and the wattage limiter, verifying that you have not exceeded the 190 watts.
The light entering the eye first passes through the cornea and then through the pupil. The cornea is the transparent outer covering of the eye that helps to focus light, while the pupil is the opening in the center of the iris that regulates the amount of light entering the eye.
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
Such light is said to be polarized.
if the light passes through something that is coloured the light changes colour to the colour that it passed through
It is called 'polarized light' .
No light will emerge from the different color paper, since all other colors except yellow have already been removed by the first one. The second one appears black.
Water is transparent because visible light can pass through it without being absorbed or scattered. This is due to the molecular structure of water, which allows light to travel through with minimal interference, enabling us to see objects on the other side of the water.

Newton discovered that white light is composed of a spectrum of colors when he passed a beam of light through a prism. This experiment led to the development of the theory of color and the understanding that light can be separated into its component colors.

Light emitting diodes will emit light when electicity is passed through them.
