A ray of red light in air (wavelength=650nm) is incident on a semicircular block of clear plastic (n=1.51 for this light), Th ray strikes the block at its center of curvature at an angle of incident of 27 degrees
Determine the wavelength of the light in the plastic box?
The source of red light is replaced with one that produces blue light (wavelength=450nm), for which the plastic has a greater index of refraction than for the red light. Qualitatively describe what happens to the reflected and refracted rays?
The semicircular block is removed and the blue light is directed perpendicular through a double slit and onto a screen. The distance between the slits is .15mm. The slits are 1.4mm from the screen
A) Calculate the distance between two adjacent bright fringes?
