If someone could please help me with this question I am having a lot of trouble.

Question 5: Derive a general equation for Ay. Using the width of the trapezoid you measured, the angle of incidence you measured, and the index of refraction for acrylic you determined in the earlier part of the activity, calculate the theoretical value for Ay and compare it to your measured value.Angle of incidence Angle of refraction Ray entering prism 44 23 Ray exiting prism 23 38 Index of refraction: 1.4335 Width of trapezoid: 3.3 cm Measured value of Ay: 0.8 cm General equation for Ay: Theoretical value of Ay
