A ray of light is traveling in glass and strikes a glass/liquidinterface. The angle of incidence is 51.0°, and the index ofrefraction of glass is n = 1.50.
(a) What must be the index of refraction of theliquid such that the direction of the light entering the liquid isnot changed?
(b) What is the largest index of refraction that the liquid canhave, such that none of the light is transmitted into the liquidand all of it is reflected back into the glass?
The earth orbits the sun once a year (3.16 x 10^7 s) in a nearlycircular orbit of radius 1.50 x 10^11 m. With respect to the sun,determine the magnitude of the earth’s centripetal acceleration.
