The elements of scientific method.
Answer to Problem 1ASA
The elements of scientific method are observation, hypothesis, experiments, theory, and law.
Explanation of Solution
The major elements of scientific method are observation, hypothesis, experiments, theory, and law. The questions arising in the mind of scientific fact seeker through the observations he or she make about the natural phenomenon occurring in the surrounding as well as in the whole universe is the basic elemental step of the scientific method. The observations and the questions lead to the thirst of finding the unknown facts. The tentative answers or an educated guess the scientist put forward towards the question raised through observation is called a hypothesis.
In order to test the correctness and validity of the hypothesis experiments are carried out under controlled conditions. It confirms whether the assumption made in the hypothesis is correct or not and whether they can be duplicated. If the hypothesis passes the experimental tests, it is possible to deduce a well-tested explanation, which is called a theory that gives proper scientific reasoning to the observed physical phenomenon.
A theory that has withstood the test for many valid experiments with great regularity and if the duplication of the tests under different physical circumstances still follow the theoretical foundation made, it is then considered as a law. The law is the final element of scientific method and it will give proper and concise statement or mathematical relation regarding the physical phenomenon.

- How can i solve this if n1 (refractive index of gas) and n2 (refractive index of plastic) is not known. And the brewsters angle isn't knownarrow_forward2. Consider the situation described in problem 1 where light emerges horizontally from ground level. Take k = 0.0020 m' and no = 1.0001 and find at which horizontal distance, x, the ray reaches a height of y = 1.5 m.arrow_forward2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3arrow_forward
- look at answer show all work step by steparrow_forwardLook at the answer and please show all work step by steparrow_forward3. As a woman, who's eyes are h = 1.5 m above the ground, looks down the road sees a tree with height H = 9.0 m. Below the tree is what appears to be a reflection of the tree. The observation of this apparent reflection gives the illusion of water on the roadway. This effect is commonly called a mirage. Use the results of questions 1 and 2 and the principle of ray reversibility to analyze the diagram below. Assume that light leaving the top of the tree bends toward the horizontal until it just grazes ground level. After that, the ray bends upward eventually reaching the woman's eyes. The woman interprets this incoming light as if it came from an image of the tree. Determine the size, H', of the image. (Answer 8.8 m) please show all work step by steparrow_forward
