Question

Light with a wavelength of 460 nm is incident on a single slit
with a slit width of 1.55 mm. A **Single Slit Diffraction
Pattern** is observed on a screen that is 1.55 m away from
the slit.

What is the **angle for the 1st order
minimum**?

What is the **angle (in degrees - written as "deg") for
the 2nd order minimum**?

How **wide (in mm)** is the **Central
Maximum**?

How **wide (in mm)** is the **First
Maximum** that is right next to the Central maximum? The
width of the First Maximum is the distance between the 1st order
minimum and the 2nd order minimum.

Answer #1

Single slit diffraction.

Coherent light of wavelength 600 nm is incident on a narrow
slit. The diffraction pattern is observed on a screen that is 4.00
m from the slit. On the screen the width of the central maximum of
the diffraction pattern is 3.00 mm. What is the width of the slit?
answer is 1.6 mm

Light of wavelength 550 nm is incident on a single slit. On a
screen 170 cm away, the central bright spot is 0.60 mm wide. What
is the width of the slit?

A.
Part 1A. Light of wavelength 640 nm is incident on a long narrow
slit. Find the angle of the first diffraction minimum if the width
of the slit is 1.5 mm. Answer in units of mrad.
Part 2A. Find the angle of the first diffraction minimum if the
width of the slit is 0.15 mm. Answer in units of mrad.
B.
Part 1B. Monochromatic light from a helium-neon laser
(wavelength 613.1 nm) is incident normally on a diffraction grating...

When a light source with wavelength of 500 nm is normally
incident to a plate with a single slit, the central diffraction
maximum observed on a screen that is 2.95 mm behind the
plate has a width w. The incident light is then changed to a source
with wavelength of 632 nm. How far behind the plate should the
screen now be placed in order to obtain the same width w for the
central diffraction maximum?

Light with a wavelength of 550 nm is incident on a single slit,
creating a diffraction pattern on a distant screen 2.5 m away. At a
point on the diffraction pattern that is 1.443 m from the central
maximum, the path length difference between the ray from the top of
the slit and the bottom of the slit results in a phase difference
of 6π radians. What is the width of the slit? (a) 1.1 µm (b) 2.2 µm
(c)...

1. monochromatic light of wavelength 540 nm from a source passes
through a slit that is 0.03mm wide. What is the width of the
central bright fringe on the diffraction pattern formed on a screen
placed at a distance of 2.00 m away from the slit?
2. Light of wavelength 500 nm is incident on a single slit of
width 0.02 mm to produce a diffraction pattern with intensity
4.00×10^-4 W/m^2 at the center of a screen placed far away...

1. A slit 1.24 mm wide is illuminated by light of wavelength 530
nm . The diffraction pattern is seen on a screen 2.19 m away Find
the distance between the first two diffraction minima on the same
side of the central maximum in meters.
2. Monochromatic light with wavelength 539 nm fall on a slit
with width 0.016 mm wide. The distance from the slit to a screen is
3.18 m. Consider a point on the screen 1.19cm from...

A diffraction pattern is appeared on a screen 130cm away from the
single slit. Calculate the fractional intensity I/Imax at a point
on the screen 5 mm from the center of the principal maximum.

slit. A diffraction pattern is appeared on a screen 130cm away from
the single slit. Calculate the fractional intensity I/Imax at a
point on the screen 5 mm from the center of the principal
maximum.
