A red laser from the physics lab is marked as producing 632.8-nm light. When light from this laser falls on two closely spaced slits, an interference pattern formed on a wall several meters away has bright red fringes spaced 5.00 mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 5.18 mm apart. Part A What is the wavelength of light produced by the pointer? Express your answer to three significant figures and include the appropriate units.

Problem 1 This problem is composed of two independent parts. For each part of the below question, fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). Part 1 Young's experiment is performed with light from excited helium atoms λ = 550 nm. Fringes are measured carefully on a screen 1.6 m away from the double slit, and the center of the 15th bright fringe is found to be 8 mm from the center of the central bright fringe and at an angle above the central axis. 0 is given by (CONSIDER THAT IS a): SMALL): b) įt 0.008 1.6 0 = d= Ay = ] Calculate , in SI units. c) [t ] Assume 0 = 0.8°.

Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at 35.25° on either side of the central bright spot. You then immerse these slits in a transparent liquid and illuminate them with the same light. Now you find that the first minima occur at 19.34° instead.

Part A The color of dyes results from the preferential absorption of certain wavelengths of light. Certain dye molecules consist of symmetric pairs of rings joined at the center by a chain of carbon atoms, as shown in (Figure 1). Electrons of the bonds along the chain of carbon atoms are shared among the atoms in the chain, but are repelled by the nitrogen-containing rings at the end of the chain. These electrons are thus free to move along the chain but not beyond its ends. They look very much like a particle in a one-dimensional box. For the molecule shown, the effective length of the "box" is 0.85 nm. Assuming that the electrons start in the lowest energy state, what is the longest wavelength this molecule will absorb? Express your answer with the appropriate units. На ?
