1. The Angle of Incidence equals the Angle of Reflection.
2. The Angle of Incidence is very SHALLOW. The light travels almost parallel to the sides of the Fiber.

Is the angle of incidence is greater than the angle of refraction when light passes from a less dense to denser medium?
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
The angle of reflection is equal to the .......?
The angle of incidence
Is the critical angle the same thing as the angle of incidence?
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
When is angle of incidence equal to angle of reflection?
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
When angle of incidence is zero?
When the angle of incidence is zero, the incident ray is perpendicular to the surface. This means the light ray travels straight along the normal and does not refract or bend. This phenomena is known as normal incidence.

What are the conditions for total internal reflection to occur?
Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence is greater than the critical angle. The critical angle is the angle of incidence at which light is refracted along the interface, rather than transmitted through it.
When a beam of light passes at an oblique angle into a material of lower optical densitythe angle of incidence is?
greater than the angle of refraction
When a beam of light passes at an oblique angle into a material of lower optical density the angle if incidence is what?
less than the angle of refraction.
When a beam of light passes into a material of lower optical density the angle of incidence is what?
The angle of incidence is less than the angle of refraction when a beam of light passes into a material of lower optical density. This is because light bends away from the normal when entering a less optically dense medium.
What angle does light travel along that causes bending in refraction?
The angle of incidence.
When measuring the angle of incidence and angle refraction the imaginary line drawn perpendicular to the surface at the point of incidence is called the?
normal.
What are the conditions necessary for refraction?
Refraction occurs when light passes from one medium to another of different optical density. The speed of light must change as it travels from one medium to another at an angle, causing it to bend. The angle of incidence must also be different from the angle of refraction for refraction to occur.
What happens when light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence?
When light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence, it continues in a straight path without bending. This is due to the fact that there is no change in the speed of light when the angle of incidence is 0 degrees.
Is the critical angle the same thing as the angle of incidence?
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection.
