In a laser experiment, a laser beam i of vacuum wavelength 1 has to propagate in air (nı = 1) through a prism which is anti-reflex (AR) coated to minimize reflections. The prism is made from a glass which has an index of refraction of n3 = 1.3). The thin film is made from a higher index material with an index of n2 = 1.4. The angle of incidence between the laser and the prism is 0 = 30°. Which...

The glass hemisphere in the figure has index of refraction ng = 1.8. A laser beam is directed radially toward the interface between the glass and a thin film of material with unknown index of refraction. The light is totally internally reflected when the angle of incidence exceeds 71°. What is the index of refraction nf of the material of the thin film? material under investigation glass

8. Visible light has wavelengths between about 1 = 400nm on the violet end of the spectrum to about l = 700nm on the red end. An anti-reflective coating with index ne = 1.2 forms a thin film on the surface of a glass lens with index n, = 1.5. (a) For a wavelength in middle of the visible-wavelength range (which appears green), find the minimum thickness of the coating for dark reflections of light entering the lens from the...

1) Two parallel beams of light are brought together on a surface. Each beam has wave length h-500 nm and intensity 1 W/m at the surface. What is the resultant intensity for each of the following path lengths or phase differences between the beams? Phase or path length difference Intensity (W/m) 0 radians (phase) T/2 radians (phase) 60 degrees (phase) 3π radians (phase) 300 nm (path length) 1000 nm (path length) 5.5 λ (path length) 2) A wave of wavelength...

(@) Spectacles are often coated to reduce reflection. The plastic of the lens has a very thin coating of some other material with different refractive index (as shown in the figure). 11 T2 Air ni Coating TLV n2 Lens n3 Figure - cross section showing three parallel layers of material (air, coating and the lens), with a light ray incident on the coating. The ray is partially reflected at the air/coating interface; the reflected ray Ti is shown....

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...
