Question

The refraction through the prisims are as shown .Pick out the WRONG statement from the following .Path of the light ray in (A) a is correct if n2>n1 and n2>n3 (B) b is correct if n1=n2 and n2>n3 (C) c is correct if n2 < n1 and n2 = n3 (D) d is correct if n1>n2 and n2 < n3

Since at the second surface light ray grazes along the surface of prism so, n2>n1 At first surface, light suffers refraction, So, n2 > n3

Q. The refraction through the prisims are as shown .Pick out the WRONG statement from the following .Path of the light ray in

$a$ is correct if $n_{2} > n_{1}$ and $n_{2} > n_{3}$

$b$ is correct if $n_{1} = n_{2}$ and $n_{2} > n_{3}$

$c$ is correct if $n_{2}$ < $n_{1}$ and $n_{2}$ = $n_{3}$

$d$ is correct if $n_{1} > n_{2}$ and $n_{2} < n_{3}$

Since at the second surface light ray grazes along the surface of prism so, $n_{2} > n_{1}$
At first surface, light suffers refraction,
So, $n_{2} > n_{3}$

a is correct if n2​>n1​ and n2​>n3​

b is correct if n1​=n2​ and n2​>n3​

c is correct if n2​ < n1​ and n2​ = n3​

d is correct if n1​>n2​ and n2​<n3​

Since at the second surface light ray grazes along the surface of prism so, n2​>n1​ At first surface, light suffers refraction, So, n2​>n3​

$a$ is correct if $n_{2} > n_{1}$ and $n_{2} > n_{3}$

$b$ is correct if $n_{1} = n_{2}$ and $n_{2} > n_{3}$

$c$ is correct if $n_{2}$ < $n_{1}$ and $n_{2}$ = $n_{3}$

$d$ is correct if $n_{1} > n_{2}$ and $n_{2} < n_{3}$

At first surface, light suffers refraction,
So, $n_{2} > n_{3}$
