The Angle of Reflection Calculator is a valuable tool used in optics and physics to determine the angle at which light or any other electromagnetic radiation reflects off a surface. By inputting the coordinates of the incident ray’s origin and the point where it intersects the surface, users can quickly calculate the angle of reflection.
Formula of Angle of Reflection Calculator
The formula used by the Calculator is straightforward:
θr = θi
Where:
- θr is the angle of reflection.
- θi is the angle of incidence.
The angle of incidence (θi) can be calculated using the arctangent function as follows:
θi = arctan((y2 - y1) / (x2 - x1))
Where:
- θi is the angle of incidence.
- (x1, y1) are the coordinates of the incident ray’s origin.
- (x2, y2) are the coordinates where the incident ray intersects the surface.
General Terms Table
| Term | Definition |
|---|---|
| Angle of Incidence | The angle between the incident ray and the normal to the surface. |
| Angle of Reflection | The angle between the reflected ray and the normal to the surface. |
| Normal | A line perpendicular to the surface at a given point. |
Adding this table of general terms provides users with helpful information and definitions related to the topic, enhancing their understanding without the need for manual calculations each time.
Example of Angle of Reflection Calculator
Let’s consider an example to illustrate the use of the Calculator:
Suppose we have an incident ray originating from the point (2, 3) and intersecting a surface at the point (5, 7). Using the calculator, we can determine the angle of reflection.
First, we calculate the angle of incidence using the formula:
θi = arctan((7 - 3) / (5 - 2)) = arctan(4 / 3) ≈ 53.13°
Since the angle of reflection is equal to the angle of incidence, the angle of reflection is also approximately 53.13°.
