While traching the path of a ray of light passing through a rectangular glass slab a student tabulated his observations. If in his experiment for two readings he takes two values ofangle ians 40^(@) and 50^(@) . What should be the correct values of anglee and angler in each case ?

1.	While traching the path of a ray of light passing through a rectangular glass slab a student tabulated his observations. If in his experiment for two readings he takes two values ofangle ians 40^(@) and 50^(@) . What should be the correct values of anglee and angler in each case ?
Answer» Solution :Case I: when ` ANGLE = 40^(@)"" anglei = anglee` then ` angle e = 40^(@) "" (SIN (i))/(sin( r)) = ` constant ` ANGLER lt 40^(@) or angler = 23^(@)` Case II. when` anglei = 50^(@)` ` angle e= 50^(@)` `anglerlt 50^(@) or angler= 30^(@)`
