Law Of Refraction By Aydar Z
Law of Refraction- by Aydar Z.
Hypothesis: During investigation, student will calculate 2 sets of Angles of Incidence & Refraction. The Hypothesis is that 2 outer angles would have very similar values (1st angle of Incidence and 2nd angle of Refraction), while 2 inner angles will also have similar values (2nd angle of Incidence and 1st angle of Refraction). This Hypothesis is based on earlier test investigations where outer angles were very similar in a range of 3 degrees and inner angles were very similar in a range of 3 degrees.
Variables:
-Independent (what is being purposely changed):
• Direction of Light Ray- During investigation, the student purposely changes direction of the ray to see the result it has on the Angle of Incidence and …show more content…
Size of Transparent Block- variable that makes a difference in how much the light travels inside the transparent block, therefore also controlling places where the light refracts back into air. If the transparent block is 10 in length by 20 in width, the ray would refract earlier than with a transparent block that has measurements of 30 in length and 25 in width. To keep investigation fair, only one block with measurements of 5cm by 7.8cm is used. This makes the conditions in each example similar, making tests fair.
4. Power from Light Box- factor that helps student to visually see light ray and record the results. This factor is not affecting the results as much, but it is needed to calculate results. If the light box has a power of 2, the light ray would be harder to see than the ray coming out of the light box with the power of 8. For the whole investigation, student used a light box projecting a ray with a power of 8. This helped the experiment a lot, as student could visually see with ease where the light refracts and moves.
5. Shape of Transparent Block- variable that makes a difference in what point of the block do the rays refract in. Compared to triangular prism, rectangular prism would have different points where the light would refract, therefore also having different angles of Incidence & Refraction. That’s why student only used rectangular prism for the experiment. This made it fair and
