yes it is light and light can
In general, red lasers tend to be more affordable than blue lasers due to differences in manufacturing costs and market demand. Blue laser diodes are more complex to produce and require higher precision, which can contribute to their higher price compared to red laser diodes.
The veins appear blue because of the way light interacts with the skin and the blood vessels. The skin absorbs different colors of light, and blue light is able to penetrate deeper into the skin, making the veins appear blue. The blood itself is actually red, but the way light is absorbed and reflected by the skin makes the veins appear blue.
Copper is the only metal I know of that has a naturally reddish lustre, though not truly red, you could more consider the color of copper to have a more of a truly tannish, orange-without-the-neon or perhaps you could call it plain brown. There are no red metals, the densest metal osmodium has a bluish lustre, the other metals are either white or yellow.
The tubes used for an IgE immunoeassy blood test are typically either a plain red-top tube or a serum separator tube (SST), which is also red-topped. The specific color may vary depending on the laboratory protocol, so it's always best to follow the instructions provided by the healthcare provider or the lab.
Blood veins appear blue in color due to the way light interacts with the skin. The skin absorbs different wavelengths of light, and blue light is able to penetrate deeper into the skin, making the veins appear blue. In reality, blood is always red, but the way light is absorbed and reflected by the skin gives the illusion of blue veins.
No whEn I was in the military and did combat missions our infrared lasers did not go through metal. Actually the wavelength of the infra red is not so high to tress pass the metal bodies, so they cannot penetrate the metal bodies. That's why metal shields are used in army for protection.
because they are
Blue lasers are preferable to red lasers primarily due to their shorter wavelength, which allows them to focus more tightly and produce higher resolution images. This characteristic makes blue lasers particularly advantageous in applications like optical storage (e.g., Blu-ray discs) and high-definition displays. Additionally, blue lasers can emit more light energy, resulting in brighter outputs compared to red lasers.
Red light does not penetrate more than gamma rays.
Glass is a transparent medium from Visible Light, which means, visible light can go through it without being blocked. Glass is NOT transparent for the entire electromagnetic spectrum though, Infra-Red light cannot go through glass (it blocks it much like a wall does to visible light!)Generally, the shorter the wavelength (as you go from red to violet to microwaves to x-ray to gamma), the more objects it can penetrate (which is the reason x-ray can penetrate your skin and flesh, but not your bones).
No, but the blue lasers recognize DVDs
As gemstones, abrasives, and in lasers.
Rotating lasers on sale can be found at Engineer Supply, Amazon, eBay, Red Back Lasers, Merchant Circle, Hultafors, Speedy Services, Lowes and Home Depot.
Rosacea can be an irritating condition to have, causing your skin to become red and irritated, but it can be treated with lasers. The pulsed dye laser (PDL) has been proven to show improvements in every patient. Other laser treatments include diode lasers, KTP lasers, CO2 lasers, Nd:YAG lasers.
no, it depends on the wavelength
Red light does not penetrate 70 meters beneath the ocean surface as it is quickly absorbed by water molecules.
Because the red ruby laser is the cheapest. Green lasers are usually more expensive. And the blue lasers found in blu-ray players are even more expensive.
