Question 449: Wave Optics

Question

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 $$\beta$$
G
, $$\beta$$
R
and $$\beta$$
B
, respectively. Then,

Accepted Answer

Fringe width, $$\beta  = {{\lambda D} \over d}$$
$$	herefore$$ $$\beta  \propto \lambda $$
As, $${\lambda _R} > {\lambda _G} > {\lambda _B}$$ $$	herefore$$ $${\beta _R} > {\beta _G} > {\beta _B}$$

Answer

$$\beta$$
G
> $$\beta$$
B
> $$\beta$$
R

Answer

$$\beta$$
B
> $$\beta$$
G
> $$\beta$$
R

Answer

$$\beta$$
R
> $$\beta$$
B
> $$\beta$$
G

Answer

$$\beta$$
R
> $$\beta$$
G
> $$\beta$$
B
