Refraction and partial internal reflection occurs
it is not the angle of total reflection, it is the critical angle. and when the angle of incidence is greater than the critical angle, total internal reflection takes place and as it is necessary for total internal reflection to take place that the ray must travel from denser to rarer medium so, when it occurs, the ray is reflected bach into the denser medium.
Then an interesting phenomenon called "Total internal reflection" takes place. Here the incident wave is totally reflected inside the medium as if it were reflected from the boundary of an opaque solid. For more details, contact at saqibahmad81@yahoo.com
The 'normal' direction is the direction perpendicular to a surface. Think of a stick with one end of it glued to a mirror. When a beam of light or a tennis ball hits the surface, the 'angle of incidence' is the angle between the normal and the direction the ball came from. The 'angle of reflection' is the angle between the normal and the direction the ball will take after the bounce. The angle of reflection will be equal to the angle of incidence. Knowing this, you can always place your bank shot exactly where you want it to go after the bounce.

The latitude of a place is the angle from the Earth's equator north or south to that place.
Light must travel from the optically denser medium to the optically less dense one. For total internal reflection to occur, the angle of incidence in the optically denser medium must be greater than the critical angle of that medium. The critical angle is that angle of incidence in the optically denser medium for which the angle of refraction is 90o.

The smallest possible angle of incidence for a light ray traveling toward a mirror is 1800. This is because then, the light ray will be either parallel or on the principal axis and hence, the angle of incidence would be 00.
Total internal reflection occurs when light travels from a medium with a higher refractive index to one with a lower refractive index, at an angle greater than the critical angle. This phenomenon happens because at angles beyond the critical angle, the light is completely reflected back into the denser medium, rather than refracted out into the less dense medium.
According to law of reflection, the angle of incidence and angle of reflection are equal. If the incident surface is smooth specular reflection takes place where the light is reflected in a single direction.
From my experience the only time I've had to do this is when testing angles of incidence and refraction. Usually the angles of incidence are predetermined, say 20, 40 and 60 degree's. A sheet of plain white paper is placed down. A glass block is set in the middle and drawn around. Make sure you draw in your normals. Use a protractor to draw the lines which are are your angles of incidence. Then place the glass block down on the outline and use a line box with a thin slit to make the light as direct as possible. You will notice the light shining through the other side of the glass block, mark these for each incidence angle. Remove your glass block and draw proper lines for the light that was shining out of the block. From here you should be able to draw lines through your glass block outline which will connect the rays of incidence and refraction. Using your protractor you will be able to find the angles of refraction accurate to 1/2 degree i think. Other light experiments such as finding the critical angle which is a limiting angle which if passed will cause total internal reflection to occur. You can find the angle of incidence which causes this to happen in which ever medium you are testing by using the formula: refractive index = 1/sin of critical angle e.g using a diamond of refractive index 2.1 you would have: 2.1 = 1/sin C SinC = 1/2.1 C = Sin^-1 (1/2.1) C = 28.4 degrees (roughly) I hope this helped, however being more specific to which light experiment you want could help!

The angle of incidence equals the angle of reflection. Always. If the surface is curved, this is still true. Now for some caveats. 1. If the "beam" has zero width, then there really is no complication. Measure angles relative to the line perpendicular to the surface and in the plane of incidence at the point the beam strikes the surface and everything works out perfectly. 2. If the beam has a finite width, then everything still works out, but the beam strikes the surface at more than one point and the reflected beam goes away from the surface at more than one point but at each point, the angle of incidence equals the angle of reflection, but the angle of incidence is different at each point on the curved surface. Still, at each point, one measures from the perpendicular to the surface at that point, just as described above. Some more technical stuff. We may say a beam has zero width if the width of the beam is very much smaller than the radius of curvature of the surface measured at the place where it strikes the surface. Under any circumstances, the beam reflected from a curved surface will spread, i.e. be dispersed at a range of angles relative to the incoming beam and that range depends on the radius of curvature of the reflecting surface. As mentioned above, this is small if the beam is narrow, but if you are observing reflection far enough from the reflecting surface, one can observe the spread. All this assumes "ray optics" where the sizes of the beam diameter and the radius of curvature are large compared to the wavelength of the light. It all gets more complicated otherwise.
No. The angle of incidence will equal the angle of reflection. No convergence will take place.
You can make your place smaller by building it smaller. There's not much to it.
