Physics Survey Report, Survey Report on Physical Knowledge

A physical survey report should be a few hundred words.

Experimental Research Report on Physics in the Second Year of Junior High School: Melting of Crystals and Amorphous Iodine Sublimation and Blooming of Iodine Aperture Imaging Characteristics of Plane Mirror Imaging Observation of convex lens imaging, all of which can be taken as an example: **Topic; **Characteristics of Plane Mirror Imaging 1 Ask a question; Is the plane mirror a real or virtual image?

Is it a zoomed-in or a zoomed-out image? Where is the image located? 2 Conjectures and assumptions; The plane mirror is a virtual image, the size of the image is equal to the size of the object, and the image and the object are on both sides of the plane mirror, respectively. 3 Make plans and design schemes; The experimental principle is the law of reflection of light and the equipment required; Candles (2 candles), flat mirror (translucent), scale, white paper, matches, Procedure; First, lay a 16-open white paper on the desktop, draw a straight line with a pencil on the middle line of the white paper, and stand the plane mirror vertically on this straight line 2. Light a candle on one side of the plane mirror, and from this side you can see the image of lighting a candle in the plane mirror, and cover the back of the plane mirror with opaque paper, and find that the image still exists, indicating that the light does not pass through the plane mirror, thus proving that the image formed behind the plane mirror is not the convergence of actual light, but a virtual image 3. Take the blackout paper, Place an unlit candle behind the flat mirror, and when the size and height of the candle placed are equal to the height of the lit candle, you can see that the unlit candle behind it also seems to be lit Explain that the size of the image behind it is equal to the size of the object 4 Use a pencil to write down the positions of the lit and unlit candles respectively, remove the flat mirror and the candle, and use a scale to measure the marks made on the white paper respectively, and measure the distance between the lit candle and the flat mirror and the distance from the unlit candle (i.e. image) to the flat mirror Compare the size of the two distances The findings are equal 5 Self-assessment The experimental process is reasonable, and the conclusions reached are correct It is best to conduct this experiment in a dark room, the phenomenon is more obvious In terms of error, there should be no error, the key is that the experimenter should operate carefully and carefully, and when using the scale, he should carefully measure 6 Communication and Application Through this experiment, we have come to the conclusion that the object in the plane mirror is like a virtual image, the size of the image is equal to the size of the object, and the distance from the image to the plane mirror is equal to the distance from the object to the plane mirror For example, when we stand in front of a mirror, we see that the image of ourselves in the mirror is a virtual image, and the distance from the image to the mirror is equal to the distance from the person to the mirror, and when we approach the mirror, we will see that the image in the mirror is also approaching us, and we can also explain why we see that the image in the water is a reflection The calm surface of the water is actually a plane mirror and so on

What is the investigation report of physics? Want a few hundred words?

An investigation report generally consists of two parts: a title and a body.

a) Title. Titles can be written in two ways. One is the standardized title format, that is, "subject of the document" plus "language", and the basic format is "investigation report on ", "investigation report on ", "investigation", etc.

The other is a free-style title, which includes three types: declarative, question-based, and a combination of main and subtitle.

b) Text. The text is generally divided into three parts: the preface, the main body, and the ending.

1 Introduction. There are several ways to write it: the first is to state the cause or purpose of the investigation, the time and place, the object or scope, the process and method, and the composition of the personnel and other circumstances of the investigation itself, from which the central question or basic conclusion can be derived; The second is to write down the historical background, general development process, current situation, main achievements, outstanding problems and other basic information of the survey object, and then put forward the central question or main viewpoint; The third is to get straight to the point and directly summarize the results of the investigation, such as affirming the practice, pointing out the problem, prompting the impact, and explaining the central content.

The preface plays the role of the finishing touch, and it should be concise and concise, and the topic should be straight to the point.

2 Subject. This is the most important part of the survey report, which details the basic situation, practices, and experiences of the survey and research, as well as the specific understandings, viewpoints, and basic conclusions drawn from the analysis of the materials obtained from the survey and research.

3 Ending. There are also many ways to write at the end, which can put forward ways to solve the problem, countermeasures or suggestions for the next step to improve the work; or summarize the main ideas of the whole text to further deepen the theme; or ask questions that provoke further thought; Or look to the future, give encouragement and call to action.

"Three birds with one stone" in the ecological banner of enterprises in the western region", "The variety structure of vegetables in a certain city", "Xing "Mother Water Cellar" Project to get rid of the dilemma of water shortage). The title is similar to the title of an official document (e.g., "Investigation on the Implementation of the Economic Responsibility System in the Technical Department of a Steel Mill", "Investigation Report on the Performance of Rural Credit Cooperatives", "Investigation on the Problems Faced by Ecological Migrants in Inner Mongolia").

The main title is generally written to reveal the topic, and the subtitle to write the event or scope of the investigation. (For example, "Revitalizing the Economy Depends on Science and Technology - A Survey on Baotou City's Relying on Scientific and Technological Personnel to Develop Industry.")

2. Signature: Write your name, grade, and class under the title. 3 Body:

It consists of two parts, namely the Introduction; The subject of the investigation report. Foreword: Briefly explain the purpose of the investigation; time and place; object or scope; what surveys have been done; What are the main points of this article?

This part mainly introduces the basic information and raises questions, and can be written in a flexible and diverse way. The main body of the investigation report: mainly the narrative and discussion of the facts.

Generally, the main situation, experience or problem of the investigation is summarized into several questions and divided into several small parts to write. Each subsection has a center, plus an ordinal number to indicate it, or add a subheading to indicate and summarize the content of the part, so that it is clear.
