Question

Diffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 8.70 cm passes through a narrow slit 12.5 cm wide. A microphone is placed 45.0 cm directly in front of the center of the slit, corresponding to point O in the figure 36.5a in the textbook. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O.At what minimal distance from O will the intensity detected by the microphone be zero?

Answer #1

Monochromatic light of wavelength 466 nm from a distant source
passes through a slit that is 0.0330 mm wide. In the resulting
diffraction pattern, the intensity at the center of the central
maximum (? = 0?) is 1.06×10?4 W/m2 . What is
the intensity at a point on the screen that corresponds to
? = 1.20?.

Monochromatic light of wavelength 477 nm from a distant source
passes through a slit that is 0.0310 mm wide. In the resulting
diffraction pattern, the intensity at the center of the central
maximum (θ = 0∘) is 1.28×10−4 W/m2 .
What is the intensity at a point on the screen that corresponds
to θ = 1.20∘. Express your answer to three significant figures and
include the appropriate units.

Monochromatic light of wavelength λ = 595 nm from a distant
source passes through a slit 0.460 mm wide. The diffraction pattern
is observed on a screen 4.00 m from the slit. In terms of the
intensity I0 at the peak of the central maximum, what is the
intensity of the light at the screen the following distances from
the center of the central maximum?
a) 1.00mm
b) 3.00mm
c) 5.00 mm

Monochromatic electromagnetic radiation with wavelength
λ from a distant source passes through a slit. The
diffraction pattern is observed on a screen 2.50 m from the
slit.

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...

Please show all your work.
A source of sound is located in a room a distance “L” from a
wall. The room temperature is 72°F. AN observer is located between
the source and the wall at 103 cm from the wall. The observer can
hear a loud sound at the 3rd harmonic and the sound
fades at the 4th harmonic.
What is the velocity of sound in the room?
What is the frequency at which the observer can hear the...

1) 2 point charges are separated by a distance of 8 cm. The left
charge is 48 mC and the right charge is -16mC. Using a full sheet
of paper: draw the 2 charges separated by 8cm, centered in the
sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet
length). [6] a) Draw field lines to indicate the electric fields
for this distribution. [4] b) Draw 3 equipotential surfaces, 1
each, that pass: -Through the...
