Question

In the figure equation of refracted ray is-

• A. $\sqrt { 3 }$x – y – $\sqrt { 3 }$ = 0
• B. $\sqrt { 3 }$x + y – $\sqrt { 3 }$ = 0
• C. $\sqrt { 3 }$x – y + $\sqrt { 3 }$ = 0
• D. None

Answer 1

Answer: (A)

$\sqrt { 3 }$x – y – $\sqrt { 3 }$ = 0

Answer 2

Slope of refracted ray x = tan 60⁰

passes through A(1, 0)

Equation y – 0 = $\sqrt { 3 }$(x – 1)

Ž $\sqrt { 3 }$x – y – $\sqrt { 3 }$ = 0
