In a prism, if the angle of the prism is 60 degrees, what is the minimum angle of deviation for light passing through it?
30 degrees
60 degrees
90 degrees
45 degrees
The minimum angle of deviation (D) for a prism is given by D = A, where A is the angle of the prism. Therefore, for a 60-degree prism, the minimum angle of deviation is 30 degrees.

Q: In a prism, if the angle of the prism is 60 degrees, what is the minimum angle of deviation for light passing through it?
Solution: The minimum angle of deviation (D) for a prism is given by D = A, where A is the angle of the prism. Therefore, for a 60-degree prism, the minimum angle of deviation is 30 degrees.
Steps: 6
Step 1: Understand what a prism is. A prism is a transparent object that bends light.
Step 2: Know the angle of the prism. In this case, the angle of the prism (A) is given as 60 degrees.
Step 3: Learn about the minimum angle of deviation (D). The minimum angle of deviation is the smallest angle at which light can pass through the prism.
Step 4: Remember the rule for minimum angle of deviation. For a prism, the minimum angle of deviation (D) is equal to half the angle of the prism (A).
Step 5: Calculate the minimum angle of deviation. Since A is 60 degrees, D = A / 2 = 60 degrees / 2 = 30 degrees.
Step 6: Conclude that the minimum angle of deviation for light passing through a 60-degree prism is 30 degrees.
