X-rays and microwaves are both forms of light; the only difference is that X-rays have a much higher frequency than microwaves. Choose which of the following statements are also true (there may be one, more than one, or none) Select one or more: a. The wavenumber k for microwaves is larger than that of X-rays b. X-rays travel faster than microwaves c. The wavelength of X-rays is shorter than that of microwaves d. microwaves travel faster than X-rays

Constants SOLUTION Light rays that enter your eye are affected by the fluid that fills the eyeball, called the vitreous humor (Figure 1). When red light from a l = 633 nm helium-neon laser enters your eye, its wavelength drops to 474 nm. Use this information to calculate the index of refraction of the vitreous humor and the speed and frequency of light passing through it. SET UP AND SOLVE We don't need to sketch this problem because we're interested...

The diagram shows light incident from above on a film of thickness d. Each of the three materials in the figure can be chosen to be air, with index of refraction n=1.00, water, with index n=1.33, or glass, with index n=1.50. Under which of the following conditions will the reflected light be completely or nearly eliminated by interference? (lambda2 refers to the wavelength of the light inside the thin film.) (Note: In the case that d<<<lambda2, you can assume the...

Remove the rays from the simulation by clicking on them and then pressing Delete. Place a Point Source at (60,180) by clicking Point Source under Tools, then clicking the simulation at (60,180). Note that the location at which the rays converge is the same as it was using the principal ray method. This is, in fact, why we use the principal ray method: it generates the convergence point using comparatively few lines. As we know from Huygens's principal, every point...
