Is there space between the layer in a laminated glass so that total internal reflection can Occur?
No.
What is totally reflecting prisms?
the defects of mirrors are overcome if 45 degree right-angled glass prisms are used.the critical angel of ordinary glass is about 42 degree and a ray falling normally on face of such prism total internal reflection occurs and the ray is turned through 90 degree .examples:totally reflecting prisms replace mirrors in good periscopes,light can also be reflected through 180 degree by a prisms this happens in binoculars.
How is the critical angle related to the refractive index of a medium?
The refractive number of a substance is a measure of how much the speed of a wave changes compared to the speed in a reference medium i.e. air or a vacuum. The critical angle is the angle of incidence above which total internal reflection occurs. When the angle of incidence of the light ray leaving the glass is less than the critical angle, the light ray speeds up on leaving the glass and is refracted away from the normal.
What do they apply to glass to make it a mirror?
the put a gloss to to the glass to make a reflection
What is the critical angle of perspex and water?
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
Is BSC optometry from vinayaka mission univ approved by ugc?
write about total internal reflection and criticle angel of a glass slab
How will you demonstrate total internal reflection?
you can demonstrate total internal reflection using a light source and glass gratings.
Is there space between the layer in a laminated glass so that total internal reflection can Occur?
No.
Is it possible to have internal reflection of light incident from air to glass?
If you mean that the light is in the glass, and the air is on the "outside", then yes. The other way it isn't possible; for total internal reflection, the material through which light travels must needs have a higher refractive index.

What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees?
The minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees is 1.414

What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
Where is Total internal reflection occurs when a beam of light Answer?
Total internal reflection occurs under two conditions; 1)the light must be traveling from more dense to less dense mediums 2)the light ray must hit the surface at an angle ,called the critical angle, or larger, as measured from a perpendicular (surface normal) line to the surfaces. The critical angle is typically in the 40 - 50 deg range, but specifically depends on the densities of the two media.
How is the critical angle related to the refractive index of a medium?
The refractive number of a substance is a measure of how much the speed of a wave changes compared to the speed in a reference medium i.e. air or a vacuum. The critical angle is the angle of incidence above which total internal reflection occurs. When the angle of incidence of the light ray leaving the glass is less than the critical angle, the light ray speeds up on leaving the glass and is refracted away from the normal.
In fiber optic cables what reflects the light back into the core?
This is done by total internal reflection. It is the result of the fact that the inner glass and the outer glass have different indices of refraction (the outside glass has a lower index of refraction).
What can produce a regular reflection?
A smooth pane of glass causes a regular reflection.
