When parallel rays hit a mirror, a phenomenon known as reflection occurs
When parallel rays hit a mirror, a phenomenon known as reflection occurs. Reflection is the bouncing back of light rays when they encounter a smooth surface like a mirror. Here’s a detailed explanation of what happens when parallel rays hit a mirror:
1. Initial Approach: Parallel rays of light approach the mirror. These rays can be imagined as being infinitely close to each other, traveling in the same direction, and at equal intervals.
2. Incident Angle: The angle between an incoming ray of light and the normal (a line perpendicular to the mirror’s surface) is called the incident angle. In the case of parallel rays, all the incident angles are equal.
3. Reflection: According to the law of reflection, the angle of incidence (the incident angle) is equal to the angle of reflection (the angle between the reflected ray and the normal). This means that when the parallel rays hit the mirror, they will all bounce off at the same angle, maintaining their parallel arrangement.
4. Reflected Rays: The reflected rays will appear to originate from a point behind the mirror called the virtual focus. This focus point is a result of the convergence of the reflected rays if they were extended behind the mirror.
5. Image Formation: The reflection of parallel rays in a mirror will form an image. In the case of a flat mirror, the image formed will be virtual, meaning it cannot be projected onto a screen. The virtual image will be the same size as the object being reflected, and it will appear to be behind the mirror at the same distance as the object is in front of the mirror. The image will also be laterally inverted, meaning left appears right and right appears left.
Overall, when parallel rays hit a mirror, they will be reflected in a way that maintains their parallel arrangement, forming a virtual image behind the mirror.
