Questions & Step-by-Step Solutions
A beam of light passes through a prism with an angle of 60 degrees. If the refractive index of the prism is 1.5, what is the angle of deviation? (2023)
Step 1: Identify the angle of the prism (A), which is given as 60 degrees.
Step 2: Identify the refractive index (n) of the prism, which is given as 1.5.
Step 3: Use the formula for angle of deviation (D), which is D = A(n - 1).
Step 4: Substitute the values into the formula: D = 60(1.5 - 1).
Step 5: Calculate (1.5 - 1) to get 0.5.
Step 6: Multiply 60 by 0.5 to find D: D = 60 * 0.5 = 30 degrees.
