If 570nm light falls on a slit 4.70
Apply tan(angle) = m(wavelength)/a
tan(angle) = 1(570 X 10-9)/(4.7 X 10-5)
angle = .695o
For the total angular width, multiply by 2
Total width = 1.39o
Light of wavelength 630nm falls on a slit that is 3.40
Laser light of wavelength 633 nm falls onto a double slit with slit separation 0.132 mm. An interference pattern is observed on a screen 2.20 m away. How far apart are the bright spots on the screen near the middle of the pattern?
Monochromatic light of wavelength 628 nm falls on a slit. If the angle between the first bright fringes on either side of the central maximum is 38 degree , estimate the slit width. answer in units of micrometers
A monochromatic beam of laser light falls on a thin slit and produces a series of bright and dark spots on a screen. If this apparatus (slit and screen) is submerged in water, the dark spots will not change their location on the screen will move away from the center spot will move toward the center spot
Light of wavelength 615 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle of 15.2
If 490 nm light falls on a slit 0.0430 mm wide, what is the full angular width of the central diffraction peak?
A beam of laser light of wavelength 632.8 nm falls on a thin slit 3.50×10−3 mm wide. After the light passes through the slit, at what angles relative to the original direction of the beam is it completely cancelled when viewed far from the slit? Type absolute values of the three least angles separating them with commas.
Light of wavelength 605 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle of 13.6° from the central maximum. Find the separation between the slits.
Light of wavelength 6.50 ✕ 102 nm falls on a double slit, and the first bright fringe of the interference pattern is observed to make an angle of 14° with the horizontal. Find the separation between the slits.
If 640-nm light falls on a slit 0.0525 mm wide, what is the angular width of the central diffraction peak? Express your answer using three significant figures.
