I'm doing a ray diagram with an arrow leaning away from a plane mirror. The rays leading from the tip of the arrow to the image on the other side of the mirror lined up perfectly, however for the rays leading from the end of the arrow I can't seem to line it all up so that angle is the same for both the reflective & incentive rays and the image (where the rays meet) is the same distance from the mirror as the object. Any pointers on what I may be doing wrong? I've looked at it a hundred times & can't figure it out. Thanks for your time :)

When drawing a ray diagram with a plane mirror, it is important to keep in mind a few key principles to ensure that your diagram accurately represents the reflection of light.

1. Start by drawing a straight line representing the plane mirror. Place an arrow above the line to represent the object.

2. Draw two diagonal lines from the tip and base of the arrow, making an equal angle with the mirror's surface. These lines represent the incident rays.

3. Use a ruler to extend the incident rays behind the mirror's surface. Remember, the angle of incidence is equal to the angle of reflection, so the extended rays should form the same angle with the mirror's normal line (a line perpendicular to the mirror's surface) as the incident rays.

4. To find the location of the image, draw a line perpendicular to the mirror's surface from the tip of the arrow. This line represents the reflected ray.

Now, let's address the problem you mentioned: aligning the image correctly with the mirror. Here are a few possible sources of error and some pointers to help you correct them:

1. Precision in drawing: Ensure that you accurately draw the rays, angle measurements, and image location. Use a sharp pencil, ruler, and protractor to achieve precise lines and angles.

2. Angle measurements: Double-check that the angles of incidence and reflection are indeed equal for the rays. Small errors in measuring angles can result in misalignment.

3. Consistency: Make sure you consistently apply the principles of reflection to each ray. For example, if the incident ray strikes the mirror at a certain distance from the mirror's surface, the reflected ray should also appear at the same distance on the opposite side of the normal line.

4. Symmetry: Confirm that your diagram is symmetrical. The image should be located equidistant from the mirror as the object. If not, reassess your construction and measurements.

Take your time and be patient with the process. If you are still having trouble, consider seeking assistance from your teacher or a classmate. Remember that practice makes perfect, and with each attempt, you will become more adept at accurately constructing ray diagrams.
