How to Draw Ray Diagram for derivation of distance between virtual
sources in
Bi-prism experiment ?
The distance d between virtual sources S1 and S2 is measured by Conjugate foci method for Bi-prism experiment. For this, lens of focal length f is introduced between bi-prism and eye piece and eye piece is set at 4f distance from slit.
Fig A
Fig B When lens is towards bi-prism at L1
position as shown in Fig A, magnified images
of S1 and S2 are
obtained and their distance d1 is measured.
When lens is towards screen at L2 position as shown in Fig B, diminished images of S1 and S2 are obtained and their
distance d2 is measured.
In these two positions the object distance u and image distance v are
interchanged.
d1
/ d = v /
u For position as in fig A
d2
/ d = u /
v For position as in fig B
Hence distance d between two virtual
sources is determined in Bi-prism experiment.
