Does a plane mirror show your actual structure?
No. It shows a simple 2 dimensional image formed by the optical wavelength EM energy (light) reflected (absorbed and re-emitted) by your body.
Why the laser go in straight line and in same size?
A Laser (Light Amplification by Stimulated Emission of Radiation) is "coherent" light. That means that all of the light is traveling in the same direction. Unlike a lightbulb, flashlight, or other "normal" light source where the light is going in all directions out from the center of the source, a Laser's light is all going in a straight line away from the source. This is why you cannot see a laser until it hits something (dust particles in the air, for example), and also why looking directly into a Laser (yes, even one of the cheap pointer types) can cause permanent damage to your eye.
Does a mirror reflect without light?
light is needed to reflect an image off a mirror...no light no reflection
When is the image said to be real or virtual image?
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
What is the geometric term of a beam from a laser?
It is a ray [of coherent light], a physical term.
