Light in a vacuum has a frequency of {eq}5.0\times 10^{15} {/eq} Hz. What is the wavelength of light in a vacuum? a. {eq}1.7\times 10^{7} {/eq} m b. 60 nm c. 600 nm d. 30 nm Light: Light is an electromagne...
Blue light is part of this visible light spectrum, and it originates from both natural and artificial sources. It has the shortest wavelength of the visible light spectrum, but the highest light energy. Wavelength is measured in nanometres, and the human eye can s...
What is Blue Light? Blue light is a color in the visible light spectrum. Blue light is a short wavelength form of light which means it produces more energy than some other wavelengths of light. Wavelengths of light and measured in nanometres (nm). Blue light falls between 400nm and 495...
Why is blue light a concern? Blue light is a high-energy visible light that is emitted by electronic devices and artificial lighting sources. It has a short wavelength and can penetrate deep into the eye, potentially causing eye strain, dryness, and fatigue. Additionally, exposure to blue ligh...
Phototherapy is a relatively inexpensive and noninvasive treatment for jaundice in a newborn. The baby’s skin is exposed to certain types of lights at a specific wavelength until the bilirubin level goes down to normal. Phototherapy has been effectively used for treating jaundice in newborn babie...
Blue light is visible light, at high energy, that is emitted by not only the sun but also digital devices. when this light reaches a certain wavelength it can cause damage to the eye when exposed to it for a long time. Do you ever rub your eyes after sitting in front of your compute...

LED light source products are different from traditional light bulbs. The light emitted by LEDs contains more blue wavelength light, and blue wavelength light will cause harm to humans. According to the evaluation report made by the European Union of Luminaire Companies (ELC) and the Eur...
The cause is exposure to light at nighttime. More specifically, it's exposure to short wavelength blue light—the kind given off by phones and tablets and pretty much any gadget with an illuminated display. Sunlight also contains blue light, which is vital during the day. It's what helps ...
