An advanced computer sends information to its various parts via infrared light pulses traveling through silicon fibers (n = 3.50). To acquire data from memory, the central processing unit sends a light-pulse request to the memory unit. The memory unit processes the request, then sends a data pulse back to the central processing unit. The memory unit takes 0.50 ns to process a request. If the information has to be obtained from memory in 2.00 ns, what is the maximum distance the memory unit can be from the central processing unit?

- Refractive Index (n) is a ratio of the speed of light in a vacuum to the speed of light in materials such as glass, water, plastic, etc. Using Snell's Law, and given an air to glass interface with and angle of incidence of 15 degrees, what will be the angle of refractance R if the refractive index of the glass is 1.5 ? Snell's Law: n; (sin I) = n, (sin R) So, Sin R = n; (sin I) / n And, R = arcsin (n; (sin I) / n,) For each angle I, find angle R: 5. I=0, R = 6. I=45, R = 7. I= 60, R = 8. I = 75, R = = arcsin (1(.259)/1.5) = arcsin (.172) = 9.9 degrees Wavelength in Air- Light- Angle of Light -Wavelength in Glass Normal 90° R Air nj-1 Glassarrow_forwardA liquid lies on top of the horizontal surface of a block of glass.

- Light travels a distance of 0.884 m in 2.00 ns in a given substance. What is the index of refraction of this substance? Express your answer to three significant figures.arrow_forwardYou may have noticed that the eyes of cats appear to glow green in low light. This effect is due to the reflection of light by the tapetum lucidum, a highly reflective membrane just behind the retina of the eye. Light that has passed through the retina without hitting photoreceptors is reflected back to the retina, thus enabling the animal to see much better than humans in low light. Suppose the eye of a cat is 1.34 cm in diameter. Assume that the light enters the eye traveling parallel to the principal axis of the lens. If some of the light reflected off the tapetum lucidum escapes being absorbed by the retina, what is the horizontal distance ?from the retina to the point where the light will be focused? Neglect any effects due to the liquid in the eye. x = ? cm The refractive index of the liquid in the eye is about 1.4. How does this affect the location of the image relative to where it would be if the eye were filled with air?arrow_forwardThe velocity of light in glass is 2 × 10' m/s.
