Laser as a substitute
for a Lighter GROUP 4 Introduction Statement of the Problem Hypothesis Significance of the Study Significance of the Study Discussion Laser is a device that generates an intense beam of light (or other electromagnetic radiation) by stimulated emission of photons from molecules. Lasers are used in drilling and cutting, alignment and guidance, and in surgery; the optical properties are exploited in holography, reading bar codes, and in recording and playing compact discs. Will the researches be able to make a laser that generates enough heat to light a candle?
Will the laser be portable enough for everyday use?
Is the laser safe to use by children?
If it goes out in the market, will it be affordable? Null: We were not able to make the laser that can generate heat due to the cheap materials used for it to become affordable if it will be released on market.

Alternative: We can make the laser work successfully if we are not going to buy cheap materials but it can make the product's price higher if it will be released on market if we use materials that is more expensive It is hoped by the researchers that the result of this study would benefit the following:

Department of Science and Technology- They will be able to provide new product that uses recycled materials as a part of a new product.

Workers in companies that produces lasers- They will have more job opportunities. Moreover, it is also hoped that through this research, it will make our inventions and experiments be more important because it can help other people by its information and be first studied in our country. Involved in the study are lasers, switch, button cell, wire, empty lighter and the other materials gathered. The investigation was conducted to find out if ordinary lasers can be transformed to a laser burner and if the use of recycled materials can be helpful as a part of this project. This research focused on the effectiveness of laser as a substitute for lighter. After conducting series of trials, it was found out that laser can be a substitute for lighters but it cannot be attained if the materials used are very cheap especially when it comes to the laser itself. Laser is a good source of heat that can light candles and other things but irresponsibility while using this kind of device might result to injuries such as burns and cuts. Scope and Limitations
