Question

Can you show the solution and steps

1.) In an experiment involving a diffraction grating where a screen is place 2 meters behind the grating and light with a wavelength lambda= 6.8x10^(-7) meters is used, the distance from the central bright fringe to the first order bright fringe is y=4.9 cm.

What is the distance between the lines of the diffraction grating in micrometers?

2.) A telescope with a lens diameter of 0.85 m is used to view two planets at the same time.

Assuming light coming from the stars has an average wavelength of 480 nm, what is the approximate minimum angular separation (theta) of the two planets in radians?

Answer #1

You have a diffraction grating with 3000 lines/cm. You also have
a light source that emits light at 2 different wavelengths, 428 nm
and 707 nm, at the same time. The screen for your experiment is 1.5
meters from the diffraction grating.
A. What is the line spacing for the grating?
B. What is the difference in the angle of the 2nd bright fringe
for each wavelength for this grating?
C. Which wavelength is closer to the center of the...

Helium atoms emit light at several wavelengths. Light from a
helium lamp illuminates a diffraction grating and is observed on a
screen 50.00 cm behind the grating. The emission at wavelength
501.5 nm creates a first-order bright fringe 21.90 cm from the
central maximum. What is the wavelength of the bright fringe that
is 26.63 cm from the central maximum?

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?

With a diffraction grating that has 3800 slits/cm, a
monochromatic light source produces 2nd order bright fringe at an
angle of 22
(a) What is the wavelength of the source? Express this in meters
and nm.
(b) Draw a diagram indicating the 1st and 2nd order bright
fringes. Indicate all the parameters.
(c) If the screen is 0.3-m away, how far (in cm) is 2nd order
bright fringe from the center?
please explain

a) Light of wavelength 585 nm passes through a slit 6.00 × 10-6
m wide and falls on a screen that is 2.28 m away. What is the
distance on the screen from the center of the central bright fringe
to the thrid dark fringe on either side?
b)
Two stars are 4.7 × 1011 m apart and are equally
distant from the earth. A telescope has an objective lens with a
diameter of 1.06 m and just detects these...

Blue light (λ = 450 nm) is used in a double slit experiment with
the slits separated
by d = 2.10 × 10^-4 m. The distance between the third order bright
fringe and the
central bright fringe is 1.93 × 10^-2 m.
(a) (3 pts.) Determine the distance between the double slit and the
screen.
(b) (3 pts.) Calculate the width of the central bright fringe, i.e.
the separation of
the two zeroth order dark fringes.
(c) (3 pts.) The...

1) For a certain diffraction grating experiment using 500-nm
light, the third dark fringe above the center line occurs at an
angle of 30° above the center line. The screen is 6.00m from the
slits. Why is this angle larger than the angle for the double-slit
experiment above using the same wavelength of light? [Ignore any
effects of single-slit diffraction.]
Group of answer choices
these diffraction grating slits are more closely-spaced
these diffraction grating slits are spaced farther apart from...

1. (a) Consider light with a wavelength of 535 nm is passing
through a diffraction grating with 924 lines per cm. At what
distance from the central bright maximum will the 1st
order maximum be seen on a screen placed 1.20 m from the
diffraction grating. Give your answer in centimeters (cm) with 3
significant figures.
(b) Unpolarized light with an intensity of 25.0 units is passed
through two successive polarizing filters, the first with its
polarization axis aligned with...

1. You have a laser with wavelength = 638.5 nm. The grating has
a slit spacing of 0 mm. What is the angle measured for n=1?
angle is in radians
Use three sig. figs.; or use N/A, if not enough information is
given.
2. You have a laser with wavelength (λ) 640 nm. You shine it
through a diffraction grating of 400 lines per millimeter. (The
diffraction grating doesn't change the wavelength, it simply
changes the direction in a matter...

1. Without corrective lenses a near sighted person can see
clearly only objects that are within 100 cm from his eyes. The
person has normal vision when wearing contacts. What type of lens
are the contact lens, and what is their focal length?
2. A person can see clearly objects that are between 1 meter and
any larger distance from their eyes. What is required to restore
their vision to normal?
3. In a youngs double slit experiment, the distance...
