- The objective and ocular of an astronomical telescope are 1.70 m apart. The ocular has a focal length of 4.55 cm. What is the telescope's angular magnification?A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.530 and is submerged in glycerin, which has an index of refraction of 1.473. What is the critical angle (in degrees) for the light ray to remain inside the fiber? Need Help? Read ItThe remains of a 99 million year old beetle have been discovered, perfectly preserved, in amber. Assume the amber is a sphere, with a circumference of 14 cm, and that amber has a refractive index of 1.55. If the image of the beetle appears to be 1.3 cm from the surface of the amber (inside the sphere) and the image is 1.1 cm tall, how tall is the actual beetle?
- A very large piece of clear ice has a cave man frozen inside it. When viewed at an anglefrom the top of the ice the cave man appears to be 1.00 ft below the surface of the ice.What is the actual depth (in units of inches) of the cave man from the top of the ice?The index of refraction of the ice is 1.309 Do NOT use i for the angle of incidence or r for the refracted angleWhat is the critical angle of incidence of a transparent medium in which light travels with 2.5 x 10^8 m/s ?
