A crown glass lens (n = 1.52) has an optical power of 4.0 d in air. What is its power in methyl alcohol (n = 1.329)?
Find the optical power and the focal lengths (a) of a thin glass lens in liquid with refractive index no-1.7 if its optical power in air is ??--5.0 D; (b) of a thin symmetrical biconvex glass lens, with air on one side and water on the other side, if the optical power of that lens in air
A small logo is embedded in a thick block of crown glass (n = 1.52), 3.20 cm beneath the top surface of the glass. The block is put under water, so there is 1.80 cm of water above the top surface of the block. The logo is viewed from directly above by an observer in air. How far beneath the top surface of the water does the logo appear to be? cm
A lens made of glass (n. - 1.52) is coated with a thin film of MgF, (n = 1.38) of thickness t. Visible light is incident normally on the coated lens as in the figure below. Glass thin film Incident An illustration shows a rectangular cross- section of glass lens oriented such that a thin film of thickness tcoats its left side. A ray of light directed to the right is perpendicularly incident upon the left side of the film....
A light ray entering an optical fiber (made from crown glass) surrounded by air is first refracted and then reflected as shown below 2 1 a. What is the minimum angle 01 (greater than or equal to 0) at which an incident ray will still be totally internally reflected? Hint for (a) Minimum angle 61 deg. (Only enter values 0 or greater.) b. What is the maximum angle 61 (smaller than 90 deg) at which an incident ray will still...
What is Brewster's angle for an air-glass (n = 1.52)surface?
A nonreflective coating (n = 1.39) covers the glass (n = 1.52) of a camera lens. Assuming that the coating prevents reflection of yellow-green light (wavelength in vacuum = 566 nm), determine the minimum nonzero thickness that the coating can have.
A ray of light propagates in air (n= 1.33) and strikes a sheet of crown glass (n=1.523). If angle of refraction in glass is 35.20, determine the angle of incidence. Show Work A) 30.30 B) 32.80 C) 35.20 D) 41.20 E) 45.0
Problem 4 Glass A lens made of glass (ng 1.52) is coated with a thin film of MgF2 (ns- 1.38) of thickness t. Visible light is incident normally on the coated lens as in the figure MgF (a) For what minimum value tmin of t will the reflected light of wavelength 540 nm (in air) be missing? Incident light (b) What is the relation giving the other values of t that will minimize the reflected light at this wavelength? Give...
