It's photons will interfere with themselves apparently. It's very strange that this happens. Particles don't interfere with themselves, but waves do.

What happens to a beam of light if you put a piece of wood in front of it?
The wood will cast a shadow, as the light can not pass through wood.
Can sound waves travel through lasers?
Yes. The laser beam is a beam of coherent light. Just photons. Meanwhile the sound wave is travelling through a medium....which isn't really true of the photons, they'll travel whether there's a medium or not. There's essentially no interaction or interference between the two. Saying that I can think of ways you could detect sound waves using lasers...but I wouldn't worry about that - sound will travel just fine through a laser beam providing it still has a medium to travel through. i.e: a laser can be present in a strong vacuum but sound won't pass through a strong vacuum - at least not to any useful degree....but that's not the laser stopping it.
Are there any ways to pass through a laser sensor without being detected?
As the question asked about "passing through" a laser sensor, the answer speaks to the breaking of the laser beam. And that's not something that you can do. Breaking the beam will trigger the sensor. If an investigator has an idea about the laser itself, it may be possible to "substitute" for the beam being used in the sensor, but most laser sensors will pick up any attempts to dump another beam in over the top of the extant one. Forget about mirrors and such. The "smart" laser sensors use a beam too small to "split" with mirrors. Rerouting with fiber optics is equally futile. What you've seen on those TV shows and in movies is pie in the sky - you can't do that. About all you can do is detect the beam and avoid it.It might be worth noting that anyone using a laser may also be using infrared IR sensors. (I would.) These sensors are notlasers and are completely passive; they emit nothing at alland cannot be "seen" in any way. (See the link below "What is a PIR alarm system?" for more details). If something is worth protecting with a laser, an IR detector would be an easy "add on" to that system. In fact, given a choice, the IR would be a better first choice.
What happens to colours of light that do not pass through filters?
is past through
How does a bar code laser scanner work?
A bar code laser scanner works by shining a bright light (laser light) at the barcode and measuring the reflected beam. In order to scan the entire barcode very quickly, the light is bounced off a spinning disk to cover the entire barcode in one pass.
How does a laser beam repair a retina?
The laser works like a sewing machine to repair a detached retina, the membrane that lines the interior of the eye. The laser beam is adjusted so that it can pass harmlessly through the lens and focus on tiny spots around the damaged area of the retina. When it is focused, the beam has the intensity to "weld" or seal the detached area of the retina back against the wall of the eyeball.

Why radar beam easily pass through ice?
Because ice is transparent.
What happens when a load is applied to the beam?
when the load is applied in the beam then deflection takes place. the nature of the deflection depends on the support provided on it

What happens where cables have to pass through a wooden joist?
Nothing happens. A hole is drilled through the joist and the wire is pulled through it.
What happens to the gold if you drink it does it stay trapped in the body or does it pass through?
The edible gold leaf will pass through your body.

How would light pass through water?
It happens by the refraction of light.
What happens when electric current is pass through a colloidal solution?
it will get hot
