Your artist friend is designing an exhibit inspired by circular-aperture diffraction. A pinhole in a red zone is going to be illuminated with a red laser beam of wavelength , while a pinhole in a violet zone is going to be illuminated with a violet laser beam of wavelength . She wants all the diffraction patterns seen on a distant screen to have the same size. For this to work, what must be the ratio of the red pinhole鈥檚 diameter to that of the violet pinhole?
Two wide slits spaced apart are illuminated by blue laser light with a wavelength of . The interference pattern is observed on a screen behind the slits. How many bright fringes are seen in the central maximum that spans the distance between the first missing order on one side and the first missing order on the other side?
A diffraction grating having diffracts visible light at .What is the light's wavelength?
A Michelson interferometer uses light from a sodium lamp. Sodium atoms emit light having wavelengths and . The interferometer is initially set up with both arms of equal length , producing a bright spot at the center of the interference pattern. How far must mirrorbe moved so that one wavelength has produced one more new maximum than the other wavelength?
FIGURE P33.56 shows the light intensity on a screen behind a single slit. The slit width is and the screen is behind the slit. What is the wavelength (in nm) of the light?
