Why does laser light travel so far?

The laser's light waves travel together with their peaks all lined up, or in phase. This is why laser beams are very narrow, very bright, and can be focused into a very tiny spot. Because laser light stays focused and does not spread out much (like a flashlight would), laser beams can travel very long distances.... view details ›

Can a laser destroy a planet?

Ultimately the planet would be melted from the outside in not the inside out, but as I said that's just not going to happen. If you had a laser powerful enough it would be so massive that it would be easier to destroy the earth by a colliding with it than by firing at it.... read more ›

Do lasers have a limit?

There's a limit to the intensity a laser can reach: the energy over time on an area. That's not a fundamental limit, but rather a practical limitation set by the materials used in the laser setup itself.... view details ›

Visible laser light can be blocked by anything that also blocks conventional light, such as a solid curtain, a wall, or even a sheet of paper.... view details ›

Can a mirror stop a laser?

The best way to stop a laser is to use a mirror to send it away or put some object in the way. The object will absorb the light from the laser much like your clothes absorb some of the light from around you.... view details ›

Can a laser go through fire?

A flame is a transparent medium for a green laser. The laser can be deviated locally because of the gas density in the flame, which induces changes of the refraction index (like a beam devited through a glass). For some specific wavelengths related to the molecule in the flame, a laser can be absorbed.... continue reading ›

Can a laser reach the clouds?

Lasers can also be used to target a single person, meaning it's a highly secure form of communication." But there is a problem: the laser beams cannot penetrate clouds and fog. So, if the weather is bad, it is impossible to transmit information using lasers.... see details ›

Can a laser pointer reach a plane?

The beam CAN hit an aircraft

The beam actually continues even if the light is no longer scattered back to your eyes. Some people have been arrested because they thought the beam could not reach an aircraft -- but it definitely can! From the air, the beam can look like this: Even a very weak beam can be a distraction.... see details ›

How strong is a laser to hit the moon?

How much power would a laser pointer need to reach the moon? According to experiments, you'd need around 0.004 YW (yottawatts) to power a laser that's strong enough to reach the surface of the moon. That's more than the available energy we have here on earth.... see more ›

We can never reach the speed of light. Or, more accurately, we can never reach the speed of light in a vacuum. That is, the ultimate cosmic speed limit, of 299,792,458 m/s is unattainable for massive particles, and simultaneously is the speed that all massless particles must travel at.... view details ›

How far can a 1000 mW laser go?

So we return to the question: “how far can I see my laser beam for?” As mentioned there will be many different factors to consider, but here is a basic guideline. 200mW green lasers will be visible for more than 10 miles and blue lasers 1,000mW or more will also be visible for 10 miles or more on a clear line of sight.... read more ›

How far can a 650nm laser go?

What happens if a laser hits your eye for a second?

Laser pointers can put out anywhere between 1 and 5 milliwatts of power, which is enough to damage the retina after 10 seconds of exposure. This can lead to permanent vision loss. That said, it can be very difficult to expose the retina to that much light for that long a time.... see more ›

How far can a 100 mW laser go?

A 100 mW visible laser has an eye injury distance (NOHD) of 231 feet. If the NOHD increased linearly along with the power, then for a 1000 mW laser (10 times the power) the NOHD would be 2,310 feet (10 times the original NOHD). Similarly, for a 2,000 mW laser the NOHD would be 4,630 feet (20 times the original NOHD).... read more ›

Can a 100mW laser burn?

So that means knowing where the burning threshold is and that threshold is at a minimum of 100mW as a general rule. That means that any laser below 100mW will be hard-pressed to burn anything and will flat out not be able to. Any laser above 100mW will be considered a burning unit, BUT, not all are created equal.... see details ›

While missiles destroy their targets instantaneously on impact, a laser must be focused on a target for a few seconds to destroy it, which may not be desirable for targets moving at thousands of kilometers per second.... view details ›

Can a laser go through a human?

A powerful enough laser could cut through the retina and burn through the person's brain tissue. However, it would take a while, and you'd have to focus the laser on a specific point. So basically, you'd have to strap the person down or immobilize them in some fashion.... view details ›

What is the most powerful laser color?
