38 based on the ray diagram and distances shown in figure 1

Thus, for the concave mirror, the reflection of principal ray 1 goes through focal point F, as shown in part (b) of the figure. For the convex mirror, the backward extension of the reflection of principal ray 1 goes through the focal point (i.e., a virtual focus). Principal ray 2 travels first on the line going through the focal point and then is reflected back along a line parallel to the ... We use the diagram shown below to answer the questions. a) angle of incidence: i = 90 - 56 = 34 °. b) angle of reflection r = i = 34 ° (by the law of reflection) c) q = 90 - r = 90 - 34 = 56 °. d) i + r = 34 + 34 = 68 °. Example 2: A ray of light is reflected by two parallel mirrors (1) and (2) at points A and B.

Based on the ray diagram and distances shown in figure 1. Following figure illustrates the ray diagram for the formation of images by a concave mirror. The position of the object is beyond the centre of curvature of the concave mirror. On the basis of given diagram, answer the questions. If the focal length of the concave mirror is 10 cm, the image formed will be at a distance _____. Figure 1 ShOWS parallel rays of light being refracted by a convex lens. Figure 1 What is distance 'X' called? / [1 mark] or Lenses can be used to form the image of an object. Complete the ray diagram in Figure 2 to show how a convex lens forms the image of the object. Use an arrow to represent the image. Do not write outside the box 2 [2 marks] The ray tracing technique shows qualitatively where the image will be located. The distance from the mirror to the image, d i, can be found from the mirror equation: do di f 1 1 1 + = do = distance from object to mirror di = distance from image to mirror f = focal length Sign Conventions: di is positive if the image is in front of the mirror ... To answer such questions, we can use a ray diagram to determine where an image is formed and what its characteristics are. EXPLORATION 23.2 – Using a ray diagram to find the location of an image Figure 23.9: An arrow located some distance in front of a plane mirror. Step 1 – An arrow is placed in front of a vertical plane mirror, as shown

The figure shows three rays from many rays that emanate from the tip of the arrow. These three rays can be traced by using the ray-tracing rules given above. Ray 1 enters the lens parallel to the optical axis and passes through the focal point on the opposite side (rule 1). Ray 2 passes through the center of the lens and is not deviated (rule 2). Some ray diagrams may also show a third ray. Convex lenses. The type of image formed by a convex. lens depends on the lens used and the distance from the object to the lens. Figure 1 shows the principal-ray diagram of the image formation by a converging lens with focal length f and object distance s = 2f/3 to the left of the lens. a. Use the equation m = y'/y = -s'/s to find the image distance s' in terms of f. b. Based on your result, is the image real or virtual? Is it to the left or right of the 39 . Show that, for a flat mirror, h i = h o. h i = h o, given that the image is the same distance behind the mirror as the distance of the object from the mirror. 40 . Use the law of reflection to prove that the focal length of a mirror is half its radius of curvature. That is, prove that. f = R / 2. f = R / 2.

Look at the ray diagram shown in the figure. The distances are measured from the pole P. The incident ray (from the object to the mirror) is from the left to the right. Thus, u, v and f are all negative (by sign convention). The u versus v graph is shown in the figure. The important points in this figure are: Distance between man and the image of chart = Distance between man and the mirror + Distance between mirror and the image of the chart = 2 m + 2.5 m = 4.5 m Question 39 A ray of light strikes a plane mirror PQ at an angle of incidence of 30 o , is reflected from the plane mirror and then strikes a second plane mirror QR placed at right angle to ...
