In this way, you can calculate the midpoint and slope of any one line. Reflection-in-action: This reflection type happens whilst you are engaged in a situation. Reflecting a graph through the X-axis, Y-axis or origin requires a fair bit of calculations on our part. After reflection ==> x = 2y2. This is a linear transformation, so it has a matrix, if you want to work it out: to work out the matrix, substitute in ( 1, 0, 0), ( 0, 1, 0) and ( 0, 0, 1) for x, and the vectors you get out will be the columns of the matrix. We start with the description of the mirror line, which would be described as y = -1 + 2x. To rotate a figure 90 degrees clockwise, use this representation: To rotate a figure 180 degrees, use this representation: Rotate the points below 90 degrees clockwise about the origin. Reflection. and are not to be submitted as it is. TIR can occur only if material 2 has a lower refractive index than material 1 and even then the incidence angle must be larger than a so called critical angle. Key vocabulary that may appear in student questions includes: translation, rotation, reflection, dilation, scale factor, pre-image, and image. If the center of rotation is the origin, input : 0 0, - Line : m p : if the line equation is y = mx+p, then input m (slope) and p (intercept) separated by a space. A reflection is sometimes called a flip or fold because the figure is flipped or folded over the line of reflection to create a new figure that is exactly the same size and shape. Therefore, the results are different for S polarization (E-field vector sticking out of the paper if you draw the interface) and P polarization (E-field vector within the incidence plane).
