Interpretation For the first part of the experiment, we put the three-surfaced mirror on top of the ray table wherein the degree scale is oriented at the top. Using one light beam towards the threesurfac surfaced ed mirror mirror,, we modify modify the angle and after after that that record recorded ed its angle of incide incidence. nce. We discovered that the angle of reflection is simply equivalent to its angle of incidence when the plane surface was utilied. !ur information further demonstrates the law of reflection wherein these two sorts of points are equivalent. For the second part of the procedure, we used two plane mirrors and set up their angle in which they are to be oriented. "y precisely inspecting the item where for this situation is a push pin, we can tally the quantity of pictures reflected. For better results, we can li#ewise calculated for the quantity of pictures framed utiliing the given equation which is I$%&'()*+-, wherein I is the number of images, and theta is the given angle. We discovered that the observed and calculated qualities ought to be equivalent. In the third part of the experiment, we were to determine the focal length and the radius of curvature. We find the focal length by utiliing the five light beams that were coordinated to the concave and convex mirrors that are to be reflected which is in this manner having an estimation of the focal length of .'cm for the convex and .cm for the concave mirror. From the s#etch that we have drawn, we discovered that the measurement of the value of the radius of curvature are ./ for both concave and convex mirrors. For the following three tables which is also the fourth part of the performed experiment, we used the candle, screen, and concave mirror in the determination of the focal length. For the fourth table, where the distance of 0 should be greater than the distance of 1 where 0 is the ob2ects distance and 1 is the picture distance. For the fifth table, we utilie the same method yet this time 1 should have a greater distance than 0. 3astly, for the sixth table wherein the distance of 1 should be equal to 0, the focal lengths were equivalent. For this experiment the possible sources of error is by not carefully measuring the values specially on the third part of the experiment wherein it is needed that the room should be dar# and the students should have a #een eye for the measurement of the focal length and radius of curvature of the concave and convex mirror otherwise, we would have a high percentage error. 4his is also the same for the fourth to the last part wherein one must ta#e note that the sie of the light of the candle reflected in the screen is not too big or not too small, 2ust the right sie.

4he goal of the experiment were met in light of the fact that we were to determine correctly the values to be measured and somehow in all the parts of the experiment wherein to be specific are as follows8 the angle of reflection, number of images reflected when utiliing a plane surface mirror, and the calculated focal length for various ob2ect and image distances. I can confidently say that the values we got are legitimate since we got a percent error and percent difference that is less than ( percent. 4he angle of incidence and the angle of reflection have the same values therefore equal since light is present and is directed toward the plane surface. 4his further supports the 3aw of 9eflection. 4he number of images formed were computed using the formula I$%&'(*theta- were compared to the number of images observed and found out they were the same values. 4he focal lengths and radius of curvature were determined using the pro2ection of the light rays using drawings and measuring its length. For the last part, we compute for the focal length using the formula8 * %%*p : %*q with varying p and q for each table. 4he angle of incidence and the angle of reflection have the same values thusly measure up to since light is available and is coordinated toward the plane surface. 4he quantity of images formed were calculated utiliing the equation I$%&'()*+- and when they were differentiated with the quantity of pictures observed, we found out that they were of the same number. 4he focal lengths and radius of curvature were determined by utiliing the pro2ection of five light beams to be reflected to the three-surfaced mirror. ; drawing was made in order for us to be able to measure its length. For the last part, we calculated for the focal length using the equation8 * %%*p : %*q with variable p and q distances for every table. 4his experiment helped me in further comprehension for the 3aw of 9eflection because we were able to see its effects in a complex manner with having different mirrors. ; real life application of plane and spherical mirrors are the side view and rear view mirrors in our cars. 4hese is helpful so that the drivers can see the cars, people, or other ob2ects on the road.
