Question

Study the following figure in which a student has marked the angle of incidence (), angle of refraction (), angle of emergence (), angle of prism () and the angle of deviation (). The correctly marked angles are:; A. and; B. , and; C. , and; D. , and(Delhi - 2016)

Answer 1

Explanation:

Study the following figure in which a student has marked the angle of incidence (\angle i),. angle of refraction (\angle r),. angle of emergence (\angle e) ,.

Answer 2

The correctly marked angles in figure are two which are given below:

• The angle of incidence and the angle of prism are correctly marked.
• The reason of the correctly marked because the angle of incidence is same as it where it always be but the angle of reflection is wrong.
• Because the angle of reflection is shown as the vertical opposite angle which is wrong.
• The angle of emergence and the angle of deviation are wrong. The correct position is when the they both interchange there position, that will become at there correct position.
• So the angle of incidence and angle of prism is correct answer.
