How do optical fibers work because of their ability to transmit light signals through total internal reflection?
Optical fibers work by transmitting light signals through total internal reflection. This means that when light enters the fiber at a certain angle, it reflects off the walls of the fiber and continues to travel through it without escaping. This allows the light signals to be transmitted over long distances without losing much of their intensity or quality.

The return of a wave to the medium for which it came when it hits a barrier?
When a wave hits a barrier and reflects back in the same medium, it is called wave reflection. This happens because the barrier cannot absorb or transmit the wave energy. The angle of reflection is equal to the angle of incidence.
Why does total internal reflection occur more in a diamond than in other gemstones?
Total internal reflection occurs more in a diamond than in other gemstones because diamonds have a higher refractive index, which causes light to bend more when passing through the diamond. This bending of light at the diamond's surface results in a greater likelihood of total internal reflection occurring within the diamond, leading to its characteristic sparkle and brilliance.
What is the type of reflection in which light striking a surface between two materials reflects totally back into the first material?
Total internal reflection is the type of reflection where light striking a surface between two materials reflects totally back into the first material because the angle of incidence is greater than the critical angle. This phenomenon is commonly observed in optical fibers and other transparent materials.
Why is the minerals ability to transmit light important?
The ability of minerals to transmit light is important because it can help identify the mineral species by observing its optical properties, such as color, transparency, and refractive index. This property is also used in various applications, including gemstone identification, mineral exploration, and scientific research.
Is the rainbow example of total internal reflection?
No. In fact, "total" internal reflection of sunlight is impossible inside a spherical raindrop.Rainbows are caused by the combined effects of refraction and (not "total") internal reflection, which concentrates the light near deflection angles of 40 to 42 degrees. Since each color is concentrated at a slightly different angle, we see arcs of color at the angles where each color is most intense.Snell's Law of Refraction says that the angle between the light and the surface normal is greater in the thinner medium (air) than the denser one (water). "Total" internal reflection occurs when light tries to exit the denser medium, but can't because the angle it would have to exit at is greater than 90 degrees. But this can't happen in a spherical water droplet, because the interior angle is always the same every time it hits, or reflects from, the surface.
Why do diamond shines?
because of total internal reflection
Why do the moon turn orange?
because of total internal reflection of light on the earth's atmosphere
Why does a semi circle not have a internal reflection?
A semicircle does not exhibit internal reflection because it is not a complete closed shape like a full circle. Internal reflection occurs when light travels through a medium and reflects off its internal surfaces, which requires a boundary that can confine the light. In a semicircle, the straight edge does not provide a reflective boundary, allowing light to escape rather than reflecting internally. Thus, without a full boundary, internal reflection cannot occur.

Rain drop undergo total internal reflection even though it is spherical.why?
Why? Because they don't. It's impossible in a sphere.

Why does total internal reflection occur in diamonds more than in other gemstones?
Because of a diamonds clarity and its molecular make-up, which is more dense than other gemstones. This is true even when a diamond and a different gemstone are cut exactly the same way.
What is the reflection of waves?
The reflection is vibration because sound is equal to vibration
Why can't you see a diffused reflection?
because a diffused reflection is a invisible wave
