If you point a laser beam at a 30 degree angle to a mirror will it reflect the same way?

This is essentially correct. A beam of light, when striking the plane of a mirror, will be reflected from that surface at the same angle as the incident beam.

How do you use snell's law to find the speed of light in jello?
Snell's law combines trigonometry and refractive indices to determine different aspects of refraction. The law is as follows: (n1)(sinX1) = (n2)(sinX2); where n1 is the refractive index of the first medium, X1 is the angle of incidence (the angle between the incident ray and the normal), n2 is the refractive index of the second medium, and X2 is the angle of refraction (the angle between the refracted ray and the normal). Setting up an experiment using jello and a laser, one can determine the index of refraction in the jello. Shine the laser at an arbitrary angle and record this angle. Then measure the refractive angle seen in the jello (this is the angle between the ray in the jello and the normal). The index of refraction for air is 1.0003. Now substitute all three values into Snell's law and solve for n2, the refractive index of jello. An index of refraction is defined as the speed of light in a vacuum divided by the speed of light in a medium. Once n2 is determine, use the following equation: n2 = c / v. Substitute n2 and the speed of light in a vacuum (which is approximately 299,792,458 meters per second), and solve for v. The value obtained will be the speed of light in jello.
What two gases combine to form a laser?
An example is the helium-neon laser.
Laser beam needs electricity or not?
All lasers require electricity to operate. The laser beam that results from operation of a laser is electromagnetic radidation, not electricity.
What is caution laser beam?
"Caution Laser Beam" is a phrase used on warning signs and labels to alert users and passersby that a laser beam may be present.
Can mirrors reflect laser beams?
Of course. Mirrors are not perfectly reflective and lasers can be built with any required power. Do you want the mirror to survive or not? Either way the answer is yes.
Can a mirror reflect a laser beam?
Yes, they can.
What is the angle of reflecting?
the angle of reflection is the angle where light bounces off the object. for example if you have a mirror the angle of reflection is the one that you can point a laser at the mirror and bounces off.
What can you use to split a laser beam?
The most common method is through the use of a beam splitter. This employs -- to keep it simple -- a partially transparent mirror placed at a 45 degree angle relative to the laser beam. Some of the beam passes through the mirror, and the rest is reflected perpendicular to the original beam by the mirror.
How do you make working model on street light?
Most objects do not give off their own light; it has to reflect light to be seen. Shine a laser onto a mirror and hold a piece of paper up in front of the mirror, watch how the rays bounce from the laser to the mirror and off onto the paper.
How can you do an Experiment on angle of reflection and angle of incidence?
Set up a light source that has narrow beam (a laser pointer is perfect for this).Point it at a mirror,measure the angle of incidence and of reflection.rotate the mirror,measure the angles,continue through many angles,tabulate and graph the results.

How the laser system works?
In the back of the machine, there is a 50-watt CO2 laser tube. There are mirrors and lenses, which get the laser beam, to the yellow lens at point 1 in the picture below. At point 2 there is a right angle mirror, that redirects the beam to point 3. At point 3, there is another right angle mirror that points the beam downward. Along with the mirror, there is a lens that focuses the beam to point 4. The lens that I used had a two-inch focusing distance. You can see there are 3 screws at point 3; the right angle mirror, and lens assembly comes out for cleaning. I don't know why, but I was surprised that the laser beam was not enclosed in its travels. You can see from the top picture on this page, that the user is protected from the working compartment, by the top lid of the machine. The window is coated to protect the user's eyes from stray laser light.
Can laser light reached at moon and can reflect back?
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
In a laser printer the laser beam is initiated and directed toward the octagonal mirror called the mirror?
"The laser beam is initiated and directed toward the octagonal mirror called the scanning mirror." (pg. 1134, Chapter 21, A+ Guide to Managing and Maintaining Your PC)
