Questions
A ray of light is incident at the glass-water interface at an angle i, it emerges finally parallel to the surface of water, then the value of would be
detailed solution
Correct option is B
For glass−water interface gμw=sin isin r . . . . . iFor water−air interface wμα=sin rsin 90o . . . .ii⇒gμw×wμα=sin isin r×sin rsin 90o=sin i⇒μwμg×μαμw=sin i⇒sin i⇒μg=1sin iTalk to our academic expert!
