The angle of approach and the reflected angle is always the same.
When the beam of a flashlight hits a mirror, it is reflected.

When a beam of light hits a mirror and bounces off, it is reflected. When light is refracted it means the light penetrates into a substance and changes the direction of its movement.
A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

Twice as large
The exact angle at which the beam and wave strike the surface is the same angle at which they are reflected.
It 'scans' the barcode with a laser beam. The beam is reflected back to the reader, and hardware calculates the time taken. The wider the bar, the longer it takes for the beam to be reflected back. The time intervals are interpreted by the computer, and compared to a stock list.
There are nine Pokémon moves that have "beam" somewhere in their name and those moves are SolarBeam which is a Grass-type attack, Ice Beam which is an ice-type attack, Signal Beam which is a Bug-type attack, Aurora Beam which is an ice-type attack, Psybeam which is a Psychic-type attack, Bubble Beam which is a water-type attack, Simple Beam which is a Normal-type move, Hyper Beam which is a Normal-type attack and Charge Beam which is an electric-type attack.
80/2 = 40 deg
15 degrees from the normal - on the other side.
Optical Code is read on the principle of beam reflection. Initially a beam is made to incident onto the optical code. As the beam gets reflected, it is analyzed for the verification of the code.
The angle of the reflected ray with the normal line to the surface of the mirror is the same as the angle of incidence. Snell's law.
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.
