"Optical Drawing" Lens and its Application PPT

【Topic Overview】

Optical drawing is a hot topic in the high school entrance examination, and the question types include fill-in-the-blank questions, experimental questions, and calculation and derivation questions. Optical drawing mainly includes: drawing using the reflection and refraction rules of light, drawing the imaging rules of plane mirrors, and drawing the special light and imaging rules of the lens. The general examination form of lens drawing is to give the lens (optical center and main light Some conditions among the elements such as axis), focus, object, image, incident ray, and outgoing ray require that the missing elements be supplemented by making a light path diagram.

Type 1: Light reflection mapping

1. (Weifang High School Entrance Examination) As shown in the figure, a beam of light forms an angle of 60° with the horizontal direction. Please place a plane mirror so that its propagation direction becomes horizontal to the right. Draw the position of the plane mirror and mark the reflection angle. degree.

Type 2 Plane mirror imaging drawing

2. As shown in the figure, the two rays a and b are rays emitted by the same luminous point S and reflected by a plane mirror. Try to find the position of the luminous point S.

Type 3: Light refraction mapping

3. A school has newly built a fountain, and a spotlight is installed in the center of the bottom of the pool. When there is no water in the pool, a beam of light from the spotlight shines on the pool wall, forming a bright spot at point S, as shown in the figure. Now fill the pool with water. When the water surface rises to position a, the person standing by the pool sees the bright spot at point P. If the water surface rises to position b, the person sees the bright spot at point Q. Please draw The location of point P and Q.

Type 4: Drawing using three special rays of the lens

4. Please complete the optical path diagram of the concave lens as shown in the figure.

5. (Changzhou High School Entrance Examination) There is a point light source S on the left side of the lens that emits two rays. After being refracted by the lens, the outgoing rays on the right side are as shown in the figure. Please draw a diagram of the light path in the figure to indicate the position of the point light source S.

Type 5: Drawing using the lens imaging principle

6. As shown in the figure, draw the image formed by AB passing through a convex lens.

7. As shown in the figure, draw the image formed by AB passing through the concave lens.

8. In the figure, L is a convex lens, CC' is its main optical axis, and O is the optical center. If the real image of object AB through the convex lens is A'B', try to use the drawing method to determine the focus F of the convex lens, and in the figure Mark the position of F.
