Question

In an experimental arrangement of a Fresnel's
biprism, monochromatic light of wavelength a
is used to produce interference fringe pattern.
On introducing a thin, transparent glass sheet
of refractive index 1,50 and thickness of 7
microns in the path of one of the interfering
beams, the central fringe of the patterns is
shifted to the position of 6th bright fringe. Then,
the wavelength 1 of the monochromatic light
used is nearly?
र
(a) 555 nm/
(b) 650 nm/
(c) 618 nm/
(d) 581 nm/​

Answer 1

Answer:

In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. Wikipedia

SI unit: kilogram meter per second kg⋅m/s
