Question

A pair of narrow, parallel slits separated by 0.300 mm is illuminated by green light (? = 546.1 nm). The interference pattern is observed on a screen 1.10 m away from the plane of the parallel slits.

ASK YOUR TEACHER Light Emitting Diodes (LEDs) are semiconductor
devices that emit light at specific wavelengths without emitting at
any other wavelengths. LEDs can be used to create lasers that are
very compact since they are a solid state device. A pair of narrow,
parallel slits separated by 0.265 mm are illuminated by a green LED
laser (λ = 546.1 nm). The interference pattern is observed on a
screen 1.60 m from the plane of the parallel slits.

A pair of slits, separated by 0.1 mm, is illuminated by light
having a wavelength of 500 nm. An interference pattern is observed
on a screen 1.20 m from the slits. (a) Draw the diagram of the
double slits and determine how far apart will adjacent bright
interference fringes on the screen? (b) What are the angles of the
first and second order fringes with respect to the zeroth order
fringe? (c) Determine the position of the first and second...

Two
narrow slits separated by 0.05 mm are illuminated with light =
540 nm. How many bands of bright lines are there between the
central maximum and the 12-cm position? (The distance between the
double slits and the screen is 1 m).

Double-Slit Interference
A pair of slits, separated by 0.120 mm, is illuminated by light
of wavelength 643 nm. An interference pattern is observed on a
screen 112 cm from the slits. Consider a point on the screen
located at y = 2.10 cm from the central maximum of the pattern…
a) What is the path difference (in nm) for the two slits at
location y?
b) What is the path difference in waves?
c) Is this a maximum, a minimum...

Two narrow slits are illuminated by a laser with a wavelength of
578 nm. The interference pattern on a screen located x = 4.50 m
away shows that the third-order bright fringe is located y = 9.10
cm away from the central bright fringe. Calculate the distance
between the two slits.
First you have to calculate the angle of the maximum. Then you
can use the formula for bright fringes of double slits.

Coherent light (600 nm) passes through two narrow slits
separated by 0.04 mm. An interference pattern is observed on a
screen at a distance 1.50 m away. (a) What is the vertical distance
of the second maximum (not counting the central maximum) from the
center of the interference pattern? (b) At what distance from the
center does the intensity fall to 1/4th of the intensity at the
center?

Orange light with ? = 615 nm strikes a pair of slits
separated by 0.620 mm .
Part A: On a screen 1.40 m away, what's the distance between the
central maximum and one of the fourth dark fringes?
Part B: On a screen 1.40 m away, what's the distance between the
third bright fringe on one side of the central maximum and the
third dark fringe on the other?
Express your answer with the appropriate units.

A monochromatic light with wavelength 480.0 nm strikes a
pair of narrow slits with spacing
0.100 mm. The first dark fringe is formed on a screen at
a vertical distance of 1.20 cm from the center of a screen placed
in front of the slit.

Light of wavelength 532 nm illuminates a pair of slits separated
by a distance of d= 0.42 mm. An interference pattern is observed on
a screen placed a distance L away (L>>d). You may use the
small angle approximation for this problem. What is the distance L
if the width of the central bright spot of the interference pattern
is delta(y) = 1.9 cm? The answer is supposed to be 15 m but i cant
figure out how to get...

White light falls on two narrow slits separated by 0.40 mm. The
interference pattern is observed on a screen 3.0 m away. What is
the separation between the first maxima for red light (l = 700 nm)
and the first maxima for violet light (l = 400 nm)?
