What else can I help you with?
Is light visible or invisible and why?
Light is both Visible, and Invisible. It depends on what frequency of light it is, and also what Species you are. For example, we Humans can't see ultra violet light but some animals, like Snakes, can see it.
Dangers of visible light?
Exposure to high-intensity visible light, such as from the sun or artificial sources, can potentially cause damage to the eyes, leading to conditions like photokeratitis or photoconjunctivitis. Prolonged exposure to blue light, a component of visible light, especially from screens, may also disrupt sleep patterns and cause digital eye strain. Additionally, visible light can contribute to skin aging and pigmentation.
Does Concrete absorbs visible light and re-radiates it as infrared energy?
No, concrete does not absorb visible light and re-radiate it as infrared energy. Concrete reflects and scatters visible light, and it absorbs some of the heat energy from sunlight. This absorbed heat can then be released over time as infrared radiation when the concrete cools down.
What energy does visible light have?
Typical light bulbs convert electrical energy into light and heat energy. The light (visible, IR and some UV) radiates away. Some we can see. The bulb heats up. This heat energy is radiated away and -- if it's not in a vacuum -- the heat is also carried away by convection.
Why are UV rays invisible?
UV rays are part of electromagnetic spectrum just like light. Some rays can be detected by the eye and some cant. The sunlight we see is the visible part of this spectrum that is why it is called visible light. Initially only light would reach the earth but now because of ozone depletion even UV rays reach the earth. So basically they are invisible because they are not part of visible light.
Who invented visible light?
Visible light doesn't have to be invented. Light is a naturally occurring phenomenon under some circumstances, and the part that us humans can see we call "visible light".
What are negative effects of visible light?
It could blind you, sunwise burn you or give you cancer
What makes matter visible?
Matter is visible because of the way it interacts with light. When light hits an object, some wavelengths are absorbed and some are reflected or transmitted. The reflected or transmitted light carries information about the object's color and appearance, making it visible to our eyes.
What are some examples of items that produce visible light?
a mirror
What are some examples of colors not visible to the human eye?
Some examples of colors not visible to the human eye include ultraviolet and infrared light.
What are some forms of radiation?
Visible light, radio, television and microwaves.
Why are objects visible?
Because they still absorb and scatter some light.
Do visible and infrared light pass through the same types of materials?
No, visible light and infrared light do not pass through the same types of materials. Visible light can pass through materials like glass and water, while infrared light can pass through materials like plastic and some fabrics.
What energy is wasted in light bulbs?
Some of the electrical energy is given off as heat not visible light.
Is all light visible?
Light is electromagnetic radiation, some visible and some not. The obvious visible spectrum is the one displayed in rainbows, which encompass the kind of light that we can see. One obvious invisible light is infrared radiation, which is basically heat. The visible spectrum ranges from 380 nm to 750 nm, in wavelength. Below the visible spectrum (less energetic) would be infrared, microwave, FM, AM, and so on. On the other side (more energetic) would be UV, X-ray, gamma-rays, etc.
What stops visible light?
Opaque objects, such as walls or clothing, can stop visible light from passing through them. Transparent objects, like glass or water, allow visible light to pass through with little obstruction. However, in some cases, certain materials can absorb or reflect visible light.
Is light visible or invisible and why?
Light is both Visible, and Invisible. It depends on what frequency of light it is, and also what Species you are. For example, we Humans can't see ultra violet light but some animals, like Snakes, can see it.
