A diver under water is looking at the overhead Sun through a diffraction grating that has 7000 lines/cm. What is the highest complete spectrum order that can be seen by the diver?Click for More...
In a double-slit experiment using monochromatic light, a screen is placed 1.25 m away from the slits, which have a separation distance of 0.0200 mm. The position of the third-order maximum is 6.35 cm from the center of the central maximum.
Find the wavelength of the light.
Find the position of the second-order maximum.
Part A = AD
Part B = They are more closely spaced than in air by a factor of 1.33.
The figure shows the interference pattern obtained in a double-slit experiment with light of wavelength λ.
Identify the fringe or fringes that result from the interference of two waves whose phases differ by exactly 2λ.
The same double-slit experiment is then immersed in water (with an index of refraction of 1.33) and repeated. When in the water, what happens to the interference fringes?
