Q: A beam of light passes through a prism with an angle of 60 degrees and has a refractive index of 1.5. What is the angle of minimum deviation?

Solution: For a prism, the angle of minimum deviation (D) can be approximated as D = A for small angles, thus D = 60 degrees.

Steps: 4

Step 1: Understand that a prism bends light. The angle of the prism is given as 60 degrees.
Step 2: Know that the angle of minimum deviation (D) is the angle at which light passes through the prism with the least bending.
Step 3: For small angles, the angle of minimum deviation (D) can be approximated to be equal to the angle of the prism (A).
Step 4: Since the angle of the prism (A) is 60 degrees, we can say that the angle of minimum deviation (D) is also approximately 60 degrees.
