A beam of white light is incident on a diffraction grating which reflects light onto a screen. Which color light has bright spots that are furthest from each other? (a) blue (b) green (c) yellow (d) red (e) violet
2. You have a diffraction grating with 2500 lines/cm. You also have a light source that emits light at 2 different wavelengths, 540 nm and 690 nm, at the same time. The screen for your experiment is 1.2 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...
495 nm laser light falls on a diffraction grating and forms an interference pattern on a wall 0.98 m behind the grating. The third bright spot is 1088 mm from the central bright spot. a) What is the spacing between the lines in the grating? d = μm b) How many lines per mm is this? lines/mm = c) If the grating were illuminated instead with a red 625 nm laser, what would be the distances to the first five...
PLEASE ANSWER 3 AND 5 SHOW ALL ALGEBRA STEPS
D) More information needed. 3. Monochromatic light falling on two slits 0.5 mm apart produces the second order fringe at 0.15 angle. The interference pattern from the slits is projected onto a screen that is 3.00 m away (a) What is the wavelength of the light used (in nm)? (b) What is the separation distance (in mm) on the screen of the second bright fringe from the central bright fringe? (c)...
28. When a narrow beam of white light is normally incident on a diffraction grating, you observe that the light to either side forms a complete spectrum from blue to red. Then you see that the spectrum repeats, but this time you see blue, then green, yellow, and purple, green, etc. The purple seems to be a mixture of red and blue light together. As you work through the problem, you conclude that blue light of wavelength 420 nm has...
You are using a hydrogen discharge tube and high quality red and blue light filters as the light source for a Michelson interferometer. The hydrogen discharge tube provides light of several different wavelengths (colors) in the visible range. The red light in the hydrogen spectrum has a wavelength of 656.3 nm and the blue light has a wavelength of 434.0 nm. When using the discharge tube and the red filter as the light source, you view a bright red spot...
A Young's interference experiment is performed with blue-green laser light. The separation between the slits is 0.500 mm, and the screen is located 3.24 m from the slits. The first bright fringe is located 3.38 mm from the center of the interference pattern. What is the wavelength of the laser light?
When laser light of wavelength 632.8 nm passes through a diffraction grating, the first bright spots occur at ± 17.0 ∘ from the central maximum. How many additional pairs of bright spots are there beyond the first bright spots? A converging lens 6.90 cm in diameter has a focal length of 310 mm If the resolution is diffraction limited, how far away can an object be if points on it transversely 4.00 mm apart are to be resolved (according to...
You are using a hydrogen discharge tube and high quality red and
blue light filters as the light source for a Michelson
interferometer. The hydrogen discharge tube provides light of
several different wavelengths (colors) in the visible range. The
red light in the hydrogen spectrum has a wavelength of 656.3 nm and
the blue light has a wavelength of 434.0 nm. When using the
discharge tube and the red filter as the light source, you view a
bright red spot...
Short Answer (6 points diffraction grating has 5150 lines diffraction per centimeter ruled on it. It is illuminated by a laser with wavelength 633 nm. The a) What is the angular separation between the first- and the third-order bright spots on the same side of the central maximum? pattern is observed on a very wide screen 2.0 meters behind the diffraction grating. b) How many bright spots would you observe on the screen?
