(1) 12 (2) 24 (3) 36 (4) 16
2. Main difference between interference and
diffraction is :
(1) Diffraction is due to interaction of light from
the same wavefront, whereas interference is the
interaction of waves from two isolated sources.
(2) Diffraction is due to interaction of light from
same wavefront, whereas the interference is
the interaction of two waves derived from the
same source
(3) Diffraction is due to interaction of waves
derived from the same source, whereas the
interference is the bending of light from the
same wavefront.
(4) Diffraction is caused by the reflected waves from
a source, whereas interference is caused due to
refraction of waves from a source.

(1) 12 (2) 24 (3) 36 (4) 16
2. Main difference between interference and
diffraction is :
(1) Diffraction is due to interaction of light from
the same wavefront, whereas interference is the
interaction of waves from two isolated sources.
(2) Diffraction is due to interaction of light from
same wavefront, whereas the interference is
the interaction of two waves derived from the
same source
(3) Diffraction is due to interaction of waves
derived from the same source, whereas the
interference is the bending of light from the
same wavefront.
(4) Diffraction is caused by the reflected waves from
a source, whereas interference is caused due to
refraction of waves from a source.

(1) 12 (2) 24 (3) 36 (4) 16
2. Main difference between interference and
diffraction is :
(1) Diffraction is due to interaction of light from
the same wavefront, whereas interference is the
interaction of waves from two isolated sources.
(2) Diffraction is due to interaction of light from
same wavefront, whereas the interference is
the interaction of two waves derived from the
same source
(3) Diffraction is due to interaction of waves
derived from the same source, whereas the
interference is the bending of light from the
same wavefront.
(4) Diffraction is caused by the reflected waves from
a source, whereas interference is caused due to
refraction of waves from a source.
