On a sunny summer day, with the sun overhead, you can stand under a tree and look on the ground at the pattern of light that has passed throughgaps between the leaves. You may see illuminated circles of varying brightness. Why are there circles, when the gaps between the leaves have irregular shapes?

- A lamp at a distance of 3 m above the point P on the floor of the room in P produces a glow of 100 lm/ m ^ 2.A) Calculate the luminous intensity of this lamp.B) Get a glow at another point on the floor at a distance of 1 m from P.arrow_forward"Light normally travels in straight line , but it ""bends"" in an optical fiber. Explain."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_forward
- The speed of light in a diamond is 12.44 million m / s, so the diamond's refractive index is * 1.24 0.24 0.42 2.41arrow_forwardIncreasing the density of a material tends to increase the index of refraction. Does light travel faster in seawater or in fresh water?arrow_forwardFiber optic cables, such as those used for high speed communication (Internet & phone services), transmit signals as light pulses through transparent cables. When viewed from one of the ends, you can see these light pulses, but when viewed from the side you can't. Why does this happen?arrow_forward
- Suppose you are outside watching the sunset. The sky is mostly clear except for a few puffy clouds right above you. The sun has just gone down over the horizon so you can no longer see it. Explain why the clouds above your head appear to be red by describing what happens to the light on its journey from the sun to the clouds and then to your eyes. (Note. Refraction, which causes light to follow a slightly curved path through the atmosphere and which was not covered in the reading, is not required to explain the answer to this question. The clouds are above you, so there can be a direct line from cloud level to the sun, even though you cannot directly see the sun at ground level.)arrow_forwardWhat actually causes the refraction of a light ray that hits a glass prism at a 45 degree angle to the surface? Compare that refraction to the same situation with a diamond prism. What’s the difference?arrow_forwardA beam of light, traveling in air, strikes a plate of transparent material at an angle of incidence of 56.0°. It is observed that the reflected and refracted beams form an angle of 90.0°. What is the index of refraction of this material? Jhy O 1.48 O 1.43 1.44 O 1.40arrow_forward
- The speed of light in any transparent medium is the same as the speed of light in a vacuum. true or false?arrow_forwardNo glass is perfectly transparent. Mainly because of reflections, about 92% of light passes through an average sheet of clear windowpane. The 8% loss is not noticed through a single sheet, but through several sheets, the loss is apparent. How much light is transmitted by a double-paned window (one with two sheets of glass)?arrow_forward43 – 44. If a ray of light from a material with n = 1.2 points at an angle of incidence of 25° would have an angle of refraction of 40° from a second material, find the index of refraction of the second material.
