After learning the refractive index concept in class, the author started wondering what will be the effect of changing temperature on the refractive index. Being a fan of swimming, concepts of apparent and real depth have always been fascinating to me. In this paper, he wanted to explore how the apparent and real depth of a liquid would change with an increase in temperature at different times of the day.
The speed of light keeps changing as light moves from one medium to another of different optical densities. For instance, the speed of a ray of light moving from a denser medium to a rarer medium will decrease. If the ray reverse in the same direction, this time moving from a rarer medium to a denser medium, its speed will increase. Ideally, when the ray moves from a denser medium to a rarer medium, its particles collect together, hence reducing speed. On the other hand, when the ray is moving from the rarer medium to a denser medium, its particles spread out, and speed increases.

- Refractive Index and its Relationship to Temperature
- The Influence of Temperature on Light Speed and Refraction
- Apparent and Real Depth Changes Due to Temperature Variations
- Snell's Law and its Application in Refractive Index Measurement
- Experimental Design and Control of Variables
Chapter Summaries
- Introduction: This section introduces the concept of refractive index and its dependence on the speed of light in different mediums. The author explores the phenomenon of apparent and real depth changes and explains how light speed varies with medium density. The introduction also outlines the research question and hypothesis.
- Research Question: This section explicitly states the research question, addressing whether the refractive index of a liquid varies with temperature.
- Research Hypothesis: The hypothesis proposes that increasing the temperature of a liquid will lead to a higher refractive index due to a decrease in density.
- Methodology: This chapter outlines the experimental design, including the independent variable (temperature and angle of incidence), dependent variable (refractive index), and control variables (amount of liquid and container size). It also provides a detailed description of the materials, procedure, and safety precautions.
