Chapter 37, Problem 37.19P
Coherent light rays of wavelength λ strike a pair of slits separated by distance d at an angle θ1 with respect to the normal to the plane containing the slits as shown in Figure P36.9. The rays leaving the slits make an angle θ2 with respect to the normal, and an interference maximum is formed by those rays on a screen that is a great distance from the slits. Show that the angle θ2 is given by

In a Young's double-slit experiment, the separation between slits is d and
the screen is a distance R from the slits. R is much greater than d and > is
the wavelength of the light. The number of bright fringes per unit width
on the screen is:
d/RX
R/dλ
Rd/λ
X/Rd
Rλ/d
A plane wave with a wavelength of 605 nm is incident normally on a single slit with a width of 3.98 x 10m. Consider waves that reach
a point on a far-away screen such that rays from the slit make an angle of 2.00° with the normal. The difference in phase for waves
from the top and bottom of the slit (in rad) is i
rad.
Your friend has been given a laser for her birthday. Unfortunately, she did not receive a manual with it and so she doesn't know the wavelength that it emits. You help her by performing a double-slit experiment, with slits separated by 0.36 mm. You find that the two m=1 bright fringes are 5.5 mm apart on a screen 1.6 mm from the slits.
What is the wavelength the laser emits?

- White light is used to illuminate the two slits in a Young's double slit experiment. The separation between the slits is b and the screen is at a distance d (>> b) from the slits. At a point on the screen directly in front of one of the slits, certain wavelengths are missing. Some of these missing wavelengths are (a) λ = b²/d (b) λ = 2b²/d (d) λ = 2b²/3d (c) λ = b²/3d 2arrow_forwardA double-slit interference pattern is created by two narrow slits spaced 0.20 mm apart.

- Consider a light wave passing through a slit and propagating toward a distant screen. Figure P37.53 shows the intensity variation for the pattern on the screen. Give a mathematical argument that more than 90% of the transmitted energy is in the central maximum of the diffraction pattern.

The index of refraction of the film is n = 1.2. Calculate the thickness of the film.arrow_forward35. Figure P36.35 shows a radio-wave transmitter and a receiver separated by a distance d - 50.0 m and both a distance A - 35.0 m above the ground. The receiver can receive sig- nals both directly from the transmitter and indirectly from signals that reflect from the ground. Assume the ground is level between the transmitter and receiver and a 180° phase shift occurs upon reflection.

- A student performs a multiple-slit interference experiment. A coherent light source illuminates multiple slits in a barrier, and the resulting interference pattern is projected on a screen that is separated from the barrier by 2.2 m. The uniform spacing between the slits is 5.0μm5.0μm. A light sensor is used to measure the intensity of the light at the screen, and the student makes the following graph of the intensity as a function of the position along the screen as measured from the center of the central maximum.

Source 1 is embedded in a material with index of refraction n1 = 1.5. The distance between source 1 and the edge of the material is 6 cm. You can assume nair = 1. At the point marked with an X, which is 9 cm from source 2 and 3 cm from the edge of the material that source 1 is embedded inside, what kind of interference will you find between EM waves from the two sources?
