Refraction and Lenses: Audio Guided Solution
Problem 2:
Consider the three diagrams below. Measure the angle of incidence and of refraction (in degrees) for each of the three diagrams.
Click to show or hide the answer!
Diagram A: angle of incidence = 20°; angle of refraction = 35°
Digram B: angle of incidence = 45°; angle of refraction = 33°
Diagram C: angle of incidence = 10°; angle of refraction = 48°
Digram B: angle of incidence = 45°; angle of refraction = 33°
Diagram C: angle of incidence = 10°; angle of refraction = 48°
- Read the problem carefully and develop a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
- Identify the known and unknown quantities and record them in an organized manner. Equate given values to the symbols used to represent the corresponding quantity - e.g., do = 24,8 cm; di = 16.7 cm; f = ???.
- Use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
- Identify the appropriate formula(s) to use.
- Perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
