Multiple Choice

A tank holds a layer of oil,of thickness T_o = 1.65 m,that floats on a layer of syrup of thickness T_s = 0.830 m,as shown in the figure.Both liquids are clear and do not mix together.A light ray,originating at the bottom of the tank at point P,crosses the oil-syrup interface at a point 0.900 m from the axis.The ray continues and arrives at the oil-air interface,2.00 m to the right of P and at the critical angle.What is the index of refraction of the syrup?

• A)1.36
• B)1.25
• C)1.94

Laboratory Experiments

Controlled tests conducted in a structured and isolated environment to investigate hypotheses by manipulating variables.

External Variables

Factors outside the individual that can influence their behavior or the outcome of a situation, including environmental, social, or economic conditions.

Independent Variables

Factors in an experiment that are deliberately changed or manipulated to investigate their effects on dependent variables.

Dependent Variables

In an experiment, these are the variables that are being tested and measured, expected to change as a result of manipulations to the independent variables.
