![]() ![]() Step 3: That’s it Now your window will display the Final Output of your Input. Step 2: For output, press the “Submit or Solve” button. Step 1: In the input field, enter the required values or functions. This is called specular reflection.įollow the below steps to get output of Reflection Calculator If the surface is smooth and sparkling, similar to glass, water or cleaned metal, the light will reflect at a similar point as it hit the surface.For a smooth surface, mirrored light beams travel a similar way. Note that in the case of a horizontal line, the vertical displacement is zero because the line runs parallel to the x-axis.Reflection is when light ricochets off an article. ![]() Note that in the case of a vertical line, the horizontal displacement is zero because the line runs parallel to the y-axis. Here you can find two calculators for an equation of a line: It also outputs slope. However, there exist different forms for a line equation. You can find an equation of a straight line given two points laying on that line. Use point slope form of all equation to write the equation of the line of reflection. The ratio of difference of y-coordinates of P and P1. The slope of the line of the reflection is the opposite reciprocal. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors. That means, Slope of P 1 P Slope of P 1 P 2. In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. From the figure, we can say that the three points P 1, P 2 and P are collinear. Let P (x, y) be a general point on the line L. Let P 1 (x 1, y 1) and P 2 (x 2, y 2) be the two given points on the line L. Note that if, then and if, then Equation of a vertical line This online calculator finds the equation of a line given two points on that line, in slope-intercept and parametric forms. Two Point Form of the Equation of a Line. ( 3, 4) ( 4, 3) Most Common Types of Reflections Reflection over the x-axis A reflection over the x-axis can be seen in the picture below in which point A is reflected to its image A'. Once we have direction vector from to, our parametric equations will be ( 3, 4) ( 4, 3) line y x ( a, b) ( b, a) Ex. ![]() This vector quantifies the distance and direction of an imaginary motion along a straight line from the first point to the second point. ![]() We need to find components of the direction vector also known as displacement vector. Let's find out parametric form of a line equation from the two known points and. Write the final line equation (we omit the slope, because it equals one):Īnd here is how you should enter this problem into the calculator above: slope-intercept line equation example Parametric line equations.Calculate the intercept b using coordinates of either point.Problem: Find the equation of a line in the slope-intercept form given points (-1, 1) and (2, 4) The line equation, in this case, becomes How to find the slope-intercept equation of a line example Note that in the case of a horizontal line, the slope is zero and the intercept is equal to the y-coordinate of points because the line runs parallel to the x-axis. The line equation, in this case, becomes Equation of a horizontal line Note that in the case of a vertical line, the slope and the intercept are undefined because the line runs parallel to the y-axis. So, once we have a, it is easy to calculate b simply by plugging or to the expression above.įinally, we use the calculated a and b to write the result as Interactive, free online graphing calculator from GeoGebra: graph functions, plot data. įor two known points we have two equations in respect to a and b line of reflection calculatorGraphing Calculator - GeoGebra. Let's find slope-intercept form of a line equation from the two known points and. If x2 x1, you cannot compute a the line is vertical and has equation x x1. The equation you need reads y a × x + b, with a an b computed as above. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. To compute the equation of the line passing through points (x1, y1) and (x2, y2): Compute the slope as a (y2-y1) / (x2-x1).
