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.

Introduction
After learning the refractive index concept in class, I 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 IA, I 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 (Bhattacharjee, 2018). 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.
Light is a form of transverse wave (Dahan et al., 2020). A transverse wave is produced when particles of the medium vibrate perpendicularly or right angles (Karami et al., 2019). The velocity of that medium is a product of wavelength and frequency. However, a shaft in transverse wave causes bending of the incident ray as it passes from one medium to another, and incidentally, a change in refracted ray. The ratio of real depth to apparent depth, the sin of the angle of incidence to sin of the angle refraction of actual speed in a medium to light of light constitutes the refractive index, n (Bhattacharjee, 2018). Therefore;
