can u explain what is the phenomenon of "total internal reflection" and which web site i could refer for it?

The maximum velocity of light is in air (strictly in vacuum).\n\nThe velocity is less in other medium.\n\nThe change in velocity from medium to medium is refraction.\n\nWhen light enters from medium 1 to medium 2, a potion of light is bounced back into the medium 1 and the remaining passes into medium 2 (Refracted). The bouncing back is reflection.\n\nThe proportion of reflection or refraction depends on the angle the ray makes at the point of incidence on the boundary.\n\nWhen light enters from glass (a medium of less velocity; optically denser medium) into air (a medium of more velocity; optically rarer medium) no portion of light is refracted (do not enter into air) at certain angles of incidences. The whole portion of light is bounced back into glass\n\nThey are TOTALLY AND INTERNALLY reflected.\n\nThere is no change in velocity and therefore total ilnternal reflection is not refraction,

The effect you speak of, really doesn't even require perfect reflection or a one-way mirror.  In our day to day experience, if you turn of the light in a closed room - it gets dark...immediately.\n\nHowever, on very short time scales, a high powered light source beamed into a cavity can result in a an internal radiation field more intense than the light source itself.\n\nIn some inertial confinement fusion experiments, scientists fire lasers into such cavities ('holraums') to achieve radiation intensities high enough to cause small capsules to implode ablatively.

Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. It can also be seen with some sound phenomena. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called diffuse reflections and unscattered reflections are called specular (mirror-like) reflections.\n\nso due to scattering only blue color is transmitted to earth\ndue to its peculiar wavelength and etc.. u will know more about the topic in ne book on optics etc...\nactually i'll tell u key words for search as\noptics sky blue wavelength electromagnetic spectrum angle deviation Rayleigh’s scattering search to get answer

First realize that since the beam is passing through something, reflection has nothing to do with it.  The only possible answer is the one that mentions refraction.

That's just a characteristic of concave mirrors.  Check this site out.  It shows you how it happens.\n\nhttp://www.physicsclassroom.com/Class/refln/U13L3a.html

'False' rainbow or secondary one forms because of TOTAL INTERNAL REFLECTION through the optical medium (which probably is the rain drops). Total internal reflection can be understood like this: sine of angle of refraction equals sine of angle of incidence into the refractive index. So, when u kep on increasing the angle of incidence, the angle of refratction also keeps on increasing till when a point comes when it esceeds 90 degrees, i.e., when the refracted ray moves back out of the refracting surface (apparently reflected), and one gets an inverted image, hence the sequence opposite of VIBGYOR. Bye. Hope this helps.

I can't explain it but if you go to www.howstuffworks.com, that might help.

A conver mirror is diverging in nature.Ligh rays incident at its extreme corners gets diverged following laws of reflection.Hence if we draw the diagram we can clearly understand that the reflected rays follow a wider path.While in case of a plane mirror the divergence is not so large.The credit to this can be given to the cuvature in convex mirror

Iridescence is an optical phenomenon characterized as the property of surfaces in which hue changes according to the angle from which the surface is viewed, such as soap bubbles and butterfly wings.\n\nIridescence is caused by multiple reflections from multi-layered, semi-transparent surfaces where the subsequent phase shift and interference of the reflections modulates the incident light (by amplifying or attenuating different frequencies). This process is the functional analog of selective wavelength attenuation as seen with the Fabry-Perot interferometer.\n\nThe word is derived in part from the Greek word iris (pl. irides), meaning "rainbow", which in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of the gods.\n\nDictionary definition:\n\nThe visual property of something having a milky brightness, exhibition of rainbowlike colors on a surface. It usually results from interference when light composed of different wavelengths is reflected from the superficial layers of organic or inorganic substances, e.g., minerals, mother-of-pearl, and the feathers of birds. Iridescence greatly enhances the value of certain gems.

Here is some empherical evidence for two negatives cancelling theory:\n\nLinear algebra can model the image you see when something is looked at through a reflecting mirror.  It is known as a linear transformation with determinate -1.  Applying the transformation twice is like looking at the image reflected off two mirrors:  it isn't backwards.  Get two mirrors and try it.  (-1)*(-1) = 1\n\n-1 is one of an infinite number of unit values in the complex numbers.  Multiplying by -1 "flipps" the direction of any arrow (vector or complex number).  Mulitplying by the value (-1) twice is two flips which takes an arrow to its original direction.  (-1)*(-1) = 1.\n\nBy the way, some other unit values in the complex numbers are called i and -i.  Multiplying by i flipps an arrow 90 degrees to the left, so it takes four such multiplications to make 1: (i)*(i)*(i)*(i) = (-1)*(-1) = 1

Same phenomenon happens when you look through a convex lens or at your reflection in a spoon. Something to do with the movement of light. It bends and shows stuff the other way around. Sorry, it's not my expertise. But that's basically how it happens.

Its all to do with the reflection orf light on concave and convex mirrored surfaces.\n\nSee this web page app. half way down for a more detailed explanation.\n\nhttp://www.mic-d.com/curriculum/lightandcolor/reflection.html
