700nm light strikes a 12,000 lines / cm diffraction grating a)
determine the angular separation of the second maximum from the
center. Explain what happens to the second one in this case.
A soap film (n=1.33) is 772 nm thick. White light strikes the
film at normal incidence. What visible wavelengths will be
constructively reflected if the film is surrounded by air on both
sides? If there is more than one answer, separate them by a
comma.
The human eye can readily detect wavelengths from about 400 nm to 700 nm. If white light illuminates a diffraction grating having 750 lines/mm, over what range of angles does the visible m = 1 spectrum extend?
A diffraction grating has 25,000 lines/cm and is illuminated
with light having a frequency of 5.0 x 1014 Hz. What are the
angles of (a) the first-order bright fringe and (b) the
second-order bright fringe?
Laser light of some wavelength λ1 shines on a diffraction
grating with 285 lines/mm at normal incidence, producing a pattern
of maxima on a large screen 1.50 m from the grating. The first
principal maximum is observed to be at an angle of 8.20° from the
central maximum.
(a) Determine the wavelength of the incident light.
(b) A second laser of wavelength λ2 is added, and it is
observed that the third principal maximum of λ2 is at the same...
You have a diffraction grating with 3000 lines/cm. You also have
a light source that emits light at 2 different wavelengths, 428 nm
and 707 nm, at the same time. The screen for your experiment is 1.5
meters from the diffraction grating.
A. What is the line spacing for the grating?
B. What is the difference in the angle of the 2nd bright fringe
for each wavelength for this grating?
C. Which wavelength is closer to the center of the...
The wheels of a car are of diameter 80 cm each. How many complete
revolutions does each wheel make in 10 minutes when the car is traveling at a speed
of 66 km per hour?
