What is white light used for?

Pulsed white light sources can be used for photography, for stroboscopes and in some scientific applications. Further, there are special applications of white light sources in scientific and technical areas such as spectroscopy, colorimetry, forensic investigations and solar cell testing.

Subsequently, why do we use white light?

White light is a mixture off all colors, in roughly equal proportions. White objects look white because they reflect back all the visible wavelengths of light that shine on them- so the light still look white to us. Colored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb. What kind of lights help with depression? Research indicates that blue light is superior to other lights in the spectrum for treating depression. Studies show that blue light can be used at a specific wavelength and frequency at less intensity than full spectrum bright light to achieve the same kind of effects.

What is the white light bulb called?

A "warm white" bulb is usually considered to be below 3000K (3000 kelvin). This is the light color provided by an incandescent bulb (2700K) or halogen bulb (2850K). As an incandescent or halogen bulb is dimmed, it becomes even warmer -- slightly orange -- in appearance. Accordingly, what is the wavelength of white light? The white light has a wavelength between the ranges of 400 ? 700 mm.

Is white light is monochromatic?

This means the light contains only one wavelength.
