Activity:
● Set up a basic experiment using a transparent beaker filled with water.
● Shine a laser pointer or torchlight from air into water at different angles.
● Measure the incident and refracted angles clearly using a protractor.
● Record observations and results carefully.
● Use ChatGPT to learn Snell’s law.
● Use Snell’s law to predict the refraction angle. Compare it with the measured refraction angle.
Results
Activity:
● Conduct similar refraction experiments using glass blocks, acrylic prisms, and other transparent materials.
● Measure and document the refracted angles carefully.
● Compare how different materials affect the bending of light.
● Can we predict the refractive index of an unknown material using incident and refraction angles of the laser pointer beam?
Results
Data 1:
n1sinθ1=n2sinθ2
n2 = n1sinθ1/sinθ2
= 1 x sin (48) / sin (31)
= 1.44
Velocity of light = 3 ×10^ 8m/s / 1.44
= 208 000 000m/s (3s.f)
Write a Python code in Google Colab to automatically calculate refractive indices based on Snell’s Law, given incident and refraction angles.
● Clearly document each experimental setup, including step-by-step photographs.
● Provide detailed sections on methodology, collected data, calculated results, and conclusions.
● Include graphs comparing refractive indices of various materials.
● Personal reflection section from group members on their learning experiences, challenges, and discoveries.
Final Outcome: Each group will present on the Google Website showcasing:
● An introduction to refraction and its applications.
● Detailed documentation of experimental setups and findings.
● Calculations and comparisons using Snell’s Law.
● Reflections on the scientific and teamwork experience.
