Two slits separated by 0.10 mm are illuminated with green light ( = 540 nm). Calculate the distance (in cm) from the central bright-region to the fifth bright band if the screen is 2.1 m away?
Monochromatic light (λ = 696 nm) is incident on a soap bubble ( = 1.40). How thick is the bubble (in nm) if destructive interference occurs in the reflected light?
Light is incident on a double-slit. The fourth bright band has an angular distance of 7.0° from the central maximum. What is the distance between the slits (in mm)? (Assume the frequency of the light is 4.3 ×1014 Hz.)
The light reflected from a soap bubble ( = 646 nm) at its center. What is the minimum thickness (in nm)?
How wide must a narrow slit be if the first diffraction minimum occurs at ±12° with laser light of 633 nm?
The light reflected from a soap bubble ( = 678 nm) at its center. What is the minimum thickness (in nm)?
Light is incident on a double-slit. The fourth bright band has an angular distance of 7.0° from the central maximum. What is the distance between the slits (in mm)? (Assume the frequency of the light is 5.1 ×1014 Hz.)
Two slits separated by 0.10 mm are illuminated with green light ( = 540 nm). Calculate the distance (in cm) from the central bright-region to the fifth bright band if the screen is 1 m away?
Two slits are separated by 0.180 mm. An interference pattern is formed on a screen 80.0 cm away by 656.3-nm light. Calculate the fraction of the maximum intensity a distance y = 0.600 cm away from the central maximum.
Helium-neon laser light (lambda = 4.50 x 10-7 m) is sent through a 0.40 mm-wide single slit. What is the width of the central maximum on a screen 1.5 m from the slit?
