A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
The reason behind the difference in color between purple light and red light is due to their different wavelengths. Purple light has a shorter wavelength and higher frequency, while red light has a longer wavelength and lower frequency. This difference in wavelength causes our eyes to perceive them as different colors.
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
White reflects most light, appearing brighter. Black absorbs most light, appearing darker. The intensity difference between them can vary depending on the specific shade of white or black being compared.
No, the brightness ratio is the numerical difference between the brightest and darkest light levels emitted by a display. It is a measure of the display's dynamic range.
The difference is their wavelengths.
There is no difference.
Difference?? There is no relation.
You can go to sleep with the light on...
The main difference between light and x-rays is that x-rays are radiation.
A light year is how far light travels in a year. A light min is how far light travels in a minute. light speed is 186000 mile/sec, at this speed you have to calculate how far it would travel in one year or one minute
The spelling of light.

You can unscrew a light bulb.

"Photo" means light, so the difference is that one zone has light and the other has no light. (The prefix "a" means "without")
A year and a year of maturity. The difference in a year of growing up is huge.
