A teacher places a fluid substance, with a refractive index of 1.65, between two horizontal panes of flat glass (each of which has n = 1.50). He then illuminates the assembly from above with monochromatic light (λ = 670 nm). What is the minimum thickness (in nm) that the liquid layer must have, if the light is to be strongly reflected back toward its source?

1. what is refractive Index 2. Why is it use in chemistry 3.What does it mean when two substances have the same refractive index?

Please exaplain in detail:1. what is refractive Index2. Why is it use in chemistry3.What does it mean when two substances have the same refractive index?For example:If our product (isoamyl acetate) has a RI=1.407 and the true values or RI of isoamyl alcohol is 1.407 and the true value for isoamyl acetate is= 1.400What does that mean?

A viscous fluid is flowing through two horizontal pipes. the pressure difference p2 - p1 between the ends of each pipe is the same. the pipes have the same radius, although one is twice as long as the other. how does the volume flow rate Qb in the longer pipe compare with the rate Qa in the shorter pipe? (A) Qb is the same as Qa (B) Qb is twice as large as Qa (C) Qb is four times as...

2. Draw a diagram (concept map) that depicts the relationships between resolution, numerical aperture, refractive index, depth of focus, magnification, working distance, and wavelength. Be sure to indicate whether relationships are positively or inversely related. Note that not all parameters need to have a relationship.

G. A car covers the first half of the distance between two places at a speed of 40 km/ hr and the second half at 60 km/hr, then can you evaluate the average speed of the car. Also Imagine a situation such that a balloon is rising vertically from rest on ground with an acceleration of 4.9 m/s2 at the end of 4 second then a stone is let fall from the balloon. Hence suggest the height of the balloon...

A land surveyor places two stakes 500 ft apart. He locates the midpoint between the two stakes and creates a perpendicular to the line that connects these two stakes. He needs to place a third stake 100 ft away along this perpendicular line. To apply the Perpendicular Bisector Theorem, the land surveyor would need to identify the location of the third stake as equidistant from the original two stakes the location of the third stake as closer to one of...

Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates (Figure \(3(a))\). The top plate is moving at speed \(V\), and the bottom plate is stationary. The distance between these two plates is \(h .\) The gravity acts in the \(z\) direction so the flow can be considered essentially two dimensional in \(x-y\) plane. Assume there acts an applied pressure gradient in the \(x\) -direction with its gradient given by, \(\partial P...

A viscous incompressible fluid is between two parallel plates (that are along the x-z plane), one of them is at y = 0 and the other at y = d. a) Considerthecasewheretheflowisstationaryinthezˆdirection, driven by a pressure gradient. Write down the Navier-Stokes equations and solve for the velocity field after imposing the relevant boundary conditions. [10 points] b) The pressure gradient is now removed, but the plate at y = d is moved in an oscillatory fashion with velocity ue−iωt in...

Two carts sit on a horizontal, frictionless track; the spring between them is compressed. The small cart has mass m, and the mass of the larger cart is M = 5.29m. NOTE: Every velocity needs magnitude and direction (given by the sign). a) Suppose the carts are initially at rest, and after the "explosion" the smaller cart is moving at velocity v = +4.88 m/s. - Find the velocity of the larger cart. V = Assume now that the mass...
