Solution: Given parameters in the problem is: The angle of incidence, i 45. Determine the refractive index of the media using the refraction formula. The reflection of triangle will look like this. Q.1: If the angle of incidence is 45 and angle of refraction is 60. Point is units from the line so we go units to the right and we end up with. Is units away so we’re going to move units horizontally and we get. Point is units from the line, so we’re going units to the right of it. We’re just going to treat it like we are doing reflecting over the -axis. Graphically, this is the same as reflecting over the -axis.
Eo is field outside and E i is inside a material. This line is called because anywhere on this line and it doesn’t matter what the value is. Dear Sir, the Definition of the shielding loss is D (dB) 20 log ( Eo (f)/Ei (f) ). Therefore, we have to use translation rule and reflection rule to. A line rather than the -axis or the -axis. Glide reflection is a composition of translation and reflection. Let’s say we want to reflect this triangle over this line. The procedure to determine the coordinate points of the image are the same as that of the previous example with minor differences that the change will be applied to the y-value and the x-value stays the same. In the end, we found out that after a reflection over the line x=-3, the coordinate points of the image are:Ī'(0,1), B'(-1,5), and C'(-1, 2) Vertical Reflection The y-value will not be changing, so the coordinate point for point A’ would be (0, 1) Since point A is located three units from the line of reflection, we would find the point three units from the line of reflection from the other side. We’ll be using the absolute value to determine the distance. Since it will be a horizontal reflection, where the reflection is over x=-3, we first need to determine the distance of the x-value of point A to the line of reflection. This is a different form of the transformation. Finding the linear transformation rule given the equation of the line of reflection equation y mx + b involves using a calculator to find angle Tan -1 (m. Since the line of reflection is no longer the x-axis or the y-axis, we cannot simply negate the x- or y-values. The linear transformation rule (p, s) (r, s) for reflecting a figure over the oblique line y mx + b where r and s are functions of p, q, b, and Tan -1 (m) is shown below.
