Is it possible to achieve total internal reflection if the object is in rarer medium?
First we should know what will be happen when the light ray goes from denser medium to rarer medium and rarer medium to denser mdeium....
1. The light refracted away from the normal (Denser to Rarer)
2. The light refracted towards the normal (Rarer to denser)
So it is not possibel to get total internal reflection whan the light travel from rarer to denser medium......
Conditions to achieve to get TIR
1. The light should travel from denser mediumt to rarer medium
2. The angle of incidence at the interface should be greater than critical angle
if you are not satisfied kindly mail me cramkum@gmail.com

When and how total internal reflection occur?
Total internal reflection occurs when a light ray travels from a denser medium to a less dense medium at an angle greater than the critical angle. This leads to all of the light being reflected back into the denser medium, rather than refracted through it. Total internal reflection is commonly observed in fiber optics and prism applications.
How does the phenomenon of internal reflection of light affect the behavior of light rays within a medium?
Internal reflection of light occurs when a light ray traveling within a medium hits the boundary with another medium at an angle greater than the critical angle. This causes the light ray to reflect back into the original medium instead of refracting out. This phenomenon affects the behavior of light rays by causing them to bounce off the boundary and stay within the medium, leading to total internal reflection.
What name is given to the angle where total internal reflection occurs?
The angle where total internal reflection occurs is called the critical angle. Beyond this angle, light traveling through a medium is completely reflected back into the same medium rather than refracted out.
Will you get a more total internal reflection with a medium that has a small critical angle or with OR that has a large critical angle?
You will get more total internal reflection with a medium that has a smaller critical angle. A smaller critical angle means that light is more likely to be reflected back into the medium rather than refracted out of it.
When does total internal refraction happen?
Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle exceeding the critical angle. This phenomenon causes the light to reflect back into the denser medium instead of refracting out of it. Total internal reflection is commonly observed in optical fibers and mirages.

When light enters in medium 2 from medium 1 the angle of incidence is always greater than the angle of refraction Could total internal reflection take place from medium 1 to medium 2?
Definitely possible asmedium 2 is found rarer compared to medium 1

How does total internal reflection occur when light is reflected from a plane mirror?
Total internal reflection occurs when light is reflected from a plane mirror at an angle greater than the critical angle. This critical angle is the angle at which light traveling from a denser medium to a less dense medium is reflected back into the denser medium instead of refracting out.
Is mirage caused by total internal reflection?
Mirages are not caused by total internal reflection. Instead, they are optical illusions caused by the bending of light rays due to temperature gradients in the atmosphere, known as atmospheric refraction. Total internal reflection occurs when light passes from a higher refractive index medium to a lower refractive index medium at an angle greater than the critical angle.
What two conditions need to be met for total internal reflection to occur?
For total internal reflection to occur, light must be traveling from a denser medium to a less dense medium, and the angle of incidence must be greater than the critical angle, which is determined by the refractive indices of the two media.
Why total internal reflection in water mixed with dettol?
Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle. Dettol added to water increases the refractive index of the water, causing total internal reflection to occur at the water-air interface. This phenomenon can be observed as increased shininess or brightness due to the reflection of light within the water.
What happens to the light ray when the angle of incidence is greater than the angle of total reflection?
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.
What are the conditions for total internal reflection to take 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.
