26.64. Set Up: If the glass plate is illuminated from above, the waves reflected at the top surface of the plate have a half-cycle reflection phase shift and the waves reflected at the bottom surface of the plate have no reflection phase shift. The condition for constructive interference is and the condition for destructive interference is Solve: (a) The visible wavelengths intensified in the reflected light are 594 nm and 424 nm. (b) The visible wavelength cancelled in the reflected light is 495 nm. 26.65. Set Up: The longest wavelength is for Solve: Reflect: for the longest wavelength in a particular order, and the longest wavelength for a given order decreases as the order m increases. 26.66. Set Up: The angular size of the object is Solve: Setting gives 26.67. Set Up: Rayleigh’s criterion says where s is the altitude and Solve: 26.68.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
