Xiaoyangshou photography

(1) Xiaoyang is imaging in the glass plate, and the images of Xiaoyang and Xiaoyang are upside down, so Xiaoyang finds himself lighting a candle with his left hand in the glass plate.

(2) Put a lighted candle in front of the glass plate, and then move an unlit candle behind the glass plate until it completely coincides with the image of the previous candle, indicating that the image of the object is equal in size.

(3) The light screen is placed at the position of the image, and the image of the candle cannot be presented on the light screen, because the flat mirror is a virtual image.

(4) the glass plate can transmit light and reflect light, so it is easy to determine the position of the image, so the glass plate is used instead of the plane mirror; The image and object formed by the plane mirror are symmetrical about the plane mirror. If the glass plate is not placed vertically in the experiment, it will bring the disadvantage that the images of B and A cannot overlap.

(5) The requirements for candles A and B in the inquiry experiment are that the shapes and sizes are exactly the same; It is mainly convenient to compare the sizes of images and objects;

(6) The scale is used in the experiment, but the scale is not used to measure the size of the image and the object, but to measure the distance between the image and the mirror, and then compare the relationship between them.

(7) If the candle moves to the mirror, the size of the candle remains the same, and the size of the image is equal, so the size of the image will not change.

Therefore, the answer is: (1) left;

(2) No ignition; Coincidence with the image of a; ?

(3) no; The plane mirror becomes a virtual image;

(4) the position of the virtual image; Images of b and a cannot overlap;

(5) the same size;

(6) the distance between the image and the object and the mirror; ?

(7) unchanged.
