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 λ=633nm 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. A) The newest laser pointers emit light with a wavelength of λ0=555nm in air. What is the wavelength of...
Very short pulses of high-intensity laser beams are used to repair detached portions of the retina of the eye. The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 810 nm and delivers 250 mW of power spread over a circular spot 510 μm in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction...

What is the speed of light in material B? 26.006 Light has a wavelength of 268.9 nm and a frequency of 7.391 × 1014 Hz when traveling through a certain substance. What is the refraction index of this medium? Use 2.998 × 108 m/s for the speed of light in a vacuum.
The speed of a light wave in a certain transparent material is 0.683 times its speed in vacuum, which is 3.00 x 108 m/s. When yellow light with a frequency of 5.25 x 1014 Hz passes through this material, what is its wavelength in nanometers? wavelength: nm
#1: What is the thinnest soap film that will strongly reflect red light from a helium-neon laser? The wavelength of this light is 633 nm in air and 470 nm in soapy water. #2 What is the wavelength of the light from a carbon dioxide laser when it is in glass with an index of refraction of 1.7? The wavelength in a vacuum is 10600 nm.

7. A ray of light has a frequency of f = 6 x 1014 Hz. It enters into a flat surface of glass from air with an angle of incidence of 0 = 30° to the surface normal. The refractive index of the glass at this frequency is 1.4. Note that the refractive index of air is 1.0, and the speed of light in air is c= 3 x 108 m/s. (a) (1 mark) What is the wavelength of the...
