Question

What is the distance between the first and second fringes produced by a diffraction grating having 4500 lines per centimeter for 605-nm light, if the screen is 1.50 m away?

Answer #1

A diffraction grating with 600 lines/mm is illuminated with
light of wavelength 510 nm. A very wide viewing screen is 2.6 m
behind the grating.
What is the distance between the two m = 1 bright fringes?
How many bright fringes can be seen on the screen?

Diffraction gratings with 6,000 lines per centimeter are readily
available. Suppose you have one, and you send a beam of white light
through it to a screen 2.00 m away. Find the angles for the
second-order diffraction of the shortest and
longest wavelengths of visible light (380 and 760 nm).
For the above problem with the diffraction gratings with 6,000
lines per centimeter through which you sent a beam of white light
to a screen 2.00 m away, what is...

A diffraction grating has a slit distance of 3 μm. At what angle
will purple light (405 nm) be seen in the 1st order? At
what angle will turquoise light (484 nm) be seen in the second
order? If the light is projected on a screen 0.3 m away, how wide
will the whole second order (400nm – 680nm) appear on the
screen?

what is the angular separation (between a grating and screen) of
the second order maximums produced by 420nm and 390 nm wavelengths
incident upon a 450 lines/mm diffraction grating

A helium-neon laser (λ=633nm) illuminates a diffraction
grating. The distance between the two m=1 bright fringes
is 30 cm on a screen 1.5 m behind the grating.
Part A
What is the spacing between slits of the grating?

24.73 . LIght is incident on a diffraction grating with 8600
lines/cm , and the pattern is viewed on a screen 2.5 m from the
grating. The incident light beam consists of two wavelengths,
4.5×10?7 m and 6.9×10?7 m .
Part A Calculate the linear distance between the first-order
bright fringes of these two wavelengths on the screen.

In the single slit diffraction pattern, the distance between
the second and fifth dark fringes is 1 cm and the distance between
the slit and the screen is 200 cm. The wavelength of the light used
is 600 nm
a) Find the width of the slit. (considering that theta is too
small, it can be accepted that tan theta = sin theta)
b) Find theta click for the third dark fringe.

The two most prominent wavelengths in the light emitted by a
hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light
from a hydrogen lamp illuminates a diffraction grating with 500
lines per mm, and the light is observed on a screen 1.50 m behind
the grating.
What is the distance between the first-order red and blue
fringes?

A diffraction grating has ? = 800&'()", and you measure a
distance h = 0.75m between the two ? = 2 bright fringes created by
a monochromatic green light source (? = 520nm).
A) (4 points) What is the distance ? from the slit plate to
the screen?
B) (5 points) How many bright fringes will show up on the
screen?
