refraction and reflection

Total Internal Reflection - Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is reflected. T..

If the angle of incidence of a ray of light traveling from a denser medium to a rarer medium is greater than the critical angle for the two media, then the ray is reflected into the denser medium and this phenomenon is described as total internal reflection. ..

A ray of light incident normally to XY goes undeviated along AB. As the angle of incidence increases, the angle of refraction also increase..

Critical angle is that angle of incidence for which a ray of light while moving from a denser to a rarer medium just grazes over the surface of separation of the two media (that is, angle of refraction = 90 o ..

Total Internal Reflection Consider an object at O in a denser medium. A ray of light incident normally to XY goes undeviated along AB. As the angle of incidence increases, the angle of refraction also increases. On increasing the angle of incidence for a particular value say ..

13. - Monochromatic light of wavelength 600 nm is incident from air to water. What are the wavelength, frequency and speed of (i) reflected, and (ii) refracted light. Refractive index of water is 1.3..

A glass plate ( m = 1.5) is used as a polarizer. Obtain the polarizing angle of incidence. What is the angle of refraction when the reflected light is plane polarize..

Telescope is an optical instrument which is used for viewing heavenly bodies and distant objects. There are basically two types of telescopes: refracting telescope reflecting telescope Refraction Telescope Reflection Telescope Refracting telescope u..

1) Observer must stand with his back towards the sun. The common centre of the concentric circular arc lies on the line joining the sun to the eye of the observer. The brightest bow seen is the primary rainbow, which is formed due to one total internal reflection and two refractionh..
