Question

- A water wave with wavelength =6m passes through two sections of a broken barrier that are 50m apart (from center to center). When the waves reach a wall 80m away and parallel to the barrier, there will be a maximum vibration of the water straight across from the center of the two sections. What is the distance from the center of this maximum vibration to the second maximum? (You can’t use the small angle approximation on this one)

Two coherent wave sources 5 cm apart make ripples in a water
tank, producing a Moire pattern. The wavelength of the waves is 3
cm. 1) Find the angle between the perpendicular bisector of the
line joining the two sources and the direction of the 1st
non-central maximum. 2) What is the direction of this 1st maximum
if the two sources operate with opposite phases?. 3) How do the
answers to 1) and 2) change if the wavelength is changed...

5. Light of wavelength 600 nm passes through two slits 0.3 mm
apart and forms an interference pattern on a screen 2 m away.

degrees), and calculate the width of a maximum on the screen (in
cm).

Light with a wavelength of 633 nm passes through a slit 6.38
?m wide and falls on a screen 1.60 m away. Find the
distance on the screen from the central bright fringe to the third
dark fringe above it. ___ cm
Monochromatic light passes through two slits separated by a
distance of 0.0332 mm. If the angle to the third maximum above the
central fringe is 3.21 degrees, what is the wavelength of the
light? __ nm

Light of wavelength 5.1×10−7m passes through two parallel slits
and falls on a screen 4.5 m away. Adjacent bright bands of the
interference pattern are 1.5 cm apart. The same two slits are next
illuminated by light of a different wavelength, and the fifth-order
minimum (m = 5) for this light occurs at the same point on the
screen as the fourth-order minimum (m = 4) for the previous
light.
What is the wavelength of the second source of light?...

Coherent monochromatic light of frequency 6.15 × 1014
Hz passes through two narrow slits and falls on a screen located
2.50 m away. The m = 20 bright fringe is at a distance of
