Young's double slit experiment is carried out by using green, red and blue light, one colour at a time. The fringe widths recorded are βG,βR and βB respectively. Then, (A) βG > βB > βR (B) βB> βG > βR (C) βR > βB > βG (D) βR > βG > βB

Fringe width β =(λ D/d) or β propto λ Now, λR > λG > λB ∴ βR > βG > βB

Q. Young's double slit experiment is carried out by using green,
red and blue light, one colour at a time. The fringe widths
recorded are $β_{G}, β_{R}$ and $β_{B}$ respectively. Then,

$β_{G} > β_{B} > β_{R}$

$β_{B} > β_{G} > β_{R}$

$β_{R} > β_{B} > β_{G}$

$β_{R} > β_{G} > β_{B}$

Fringe width $β = \frac{λ D}{d} or β \propto λ$
Now, $λ_{R} > λ_{G} > λ_{B}$
$∴ β_{R} > β_{G} > β_{B}$

Q. Young's double slit experiment is carried out by using green, red and blue light, one colour at a time. The fringe widths recorded are βG​,βR​ and βB​ respectively. Then,

βG​>βB​>βR​

βB​>βG​>βR​

βR​>βB​>βG​

βR​>βG​>βB​
