yellow light flashlight
Yellow light is not the ordinary yellow light emitted by traditional flashlights using incandescent bulbs. The light emitted by an incandescent light bulb is strictly a kind of white light, but it is warm yellow due to the low color temperature.
White light is a mixture of red, orange, yellow, green, blue, ingot, and purple. It is a mixed color. The yellow light here is monochromatic yellow, without mixing. Light is essentially an electromagnetic wave of a certain wavelength. When electromagnetic waves propagate in the air, there are five forms of direct reflection, reflection, transmission, refraction, and scattering. Due to its specific wavelength, yellow light is the color light that refracts and scatters the least in all visible light.Therefore, the yellow light has the strongest penetration, and the yellow light travels farther than other visible light under the same conditions.
This is why the traffic light is yellow, and the fog light of the car is yellow. The outdoor environment at night is usually accompanied by moisture and mist, and a Ultrfire yellow light flashlight is needed.Let Ultrafire yellow light flashlight become your safety guarantee.
