Q.16. In the diagram a ray is passing through a broken prism, find angular deviation for the ray


(1) 105 °
(2) 30 °
(3) 60 °
(4) 15 °

Dear student,To find the angle of deviation we will consider it as a complete prism.The angle A of  this prism will be given by,A=180-30-60=90oAngle of deviation(δ)=i1+i2-Ai1=45 degreei2=60degreeδ=45+60-90=15oOption (4) is correct.Regards
