"Plane Mirror Imaging" PPT Courseware on Light Phenomenon (Lesson 1)

The first part of the content: Practice on classification of knowledge points

Knowledge point 1: Explore the characteristics of plane mirror imaging

1. When Xiaonan was doing the experiment of "exploring the imaging of plane mirrors", he placed a glass plate vertically on a horizontal platform, then took two identical candles A and B, lit candle A in front of the glass plate, and observed, as shown in Figure 4- As shown in 3-1. In this experiment:

(1) The purpose of Xiaonan choosing a glass plate instead of a plane mirror for the experiment is _______________.

(2) The function of the scale in the experiment is to facilitate the comparison of the __________________ relationship between images and objects.

(3) The reason for selecting two identical candles is to compare the relationship between the image and the object.

(4) Remove the candle B at the back and place a light screen at its location, then ______ (optional "can" or "cannot") receive the image of the candle on the light screen.

(5) When Xiaonan gradually moves candle A away from the glass plate, its image size _____ (choose "get bigger", "get smaller" or "unchanged").

2. As shown in Figure 4-3-2, two identical candles and a glass plate are used to explore the imaging characteristics of a plane mirror. Which of the following statements is correct ()

A． The brighter the classroom, the better the results

B. Try to use thinner glass plates for experiments

C. For a clear image, both candles should be lit

D. When the glass plate is not placed on a vertical and horizontal plane, the image of the candle flame is not the same size as the candle flame.

3． As shown in Figure 4-3-3, the correct representation of the image of a clown in a plane mirror is ()

Knowledge point 2 Virtual image

4. As shown in Figure 4-3-4, the image formed by a plane mirror is formed by the intersection of __________ of reflected light, so the image formed by a plane mirror is a ____ (optional "real" or "virtual") image.

5. Miao Hong stands 3 m in front of the plane mirror. The distance between her and the image is ___m. Now place a wooden board with the same size as the mirror surface 1 m behind the mirror, as shown in Figure 4-3-5. When she ______ (optional "can still" or "can't") see her own image in the mirror.

Knowledge point 3 Application of plane mirror

6. Figure 4-3-6 is a schematic diagram of a periscope. The image of an object seen by an observer through the periscope is ()

A． Inverted, equal-sized virtual image

B. Inverted, equal-sized real image

C. Upright, equal-sized virtual image

D. Inverted, reduced virtual image

7. As shown in Figure 4-3-7, there is a plane mirror against the wall on the floor of the shoe store. For the convenience of customers, the clerk usually does not set θ to 90°. Which of the following statements is correct ()

A． What is formed in the mirror is an upright, equal-sized real image.

B. The mirror image becomes smaller when the person is farther away from the plane, and the mirror image becomes larger when the person is closer to the plane.

C. The plane mirror is placed at an angle so that the light reflected from the customer's feet can enter the customer's eyes after being reflected by the plane mirror.

D. Because the plane mirror is small, a person cannot be completely imaged in the mirror.

8. Regarding the imaging of plane mirrors, which of the following statements is correct ()

A． The principle of imaging by plane mirror is the reflection of light

B. The image formed by the plane mirror is on the plane mirror. The image we see through the plane mirror is the real image.

C. The larger the plane mirror, the closer the object is to the plane mirror, and the larger the image will be.

D. When an object is larger than a plane mirror, it is impossible for the object to form a complete image in the plane mirror

9. The correct plane mirror image in Figure 4-3-8 is ()

10. When checking vision, the eye chart is placed on the back and top of the subject's head, and the subject identifies the image in the mirror on the opposite wall (as shown in Figure 4-3-9). The distance between the image of the eye chart in the mirror and the person being measured is ()

A． 4.2m

B. 2.7 m

C. 4.6 m

D. 3.8 m

11． A plane mirror is fixed on the horizontal table at an angle of 45°, as shown in Figure 4-3-10. A small ball rolls towards the plane mirror on the table at a constant speed at a speed of 1 m/s. The ball is in the plane mirror. like()

A． Moving vertically upward at a speed of 1 m/s

B. Moving vertically downward at a speed of 1 m/s

C. Moving vertically upward at a speed of 2 m/s

D. Moving vertically downward at a speed of 2 m/s
