A ray of light, incident on an equilateral glass prismmu_(g) = sqrt(3)) moves parallel to the base line of the prims inside it. Find the angle of incidence for this ray. |
Answer» SOLUTION : From the diagram, `r = 30^(@)` Also `n_(21) = ( sin i) /( sin r )` `rArrsqrt(3) = ( sin i)/(sin 30)` `RARR sin i=(sqrt(3) xx (1)/(2)` `rArr i = 60^(@)` |
