What else can I help you with?
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
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.
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.
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.
When light travels from a denser medium to a rarer medium it bends away from the normal Is it possible for the light ray to reflect back in the same medium?
Yes, when light travels from a denser medium to a rarer medium and strikes the interface at an angle greater than the critical angle, total internal reflection can occur. In this case, the light ray reflects back into the denser medium instead of refracting into the rarer medium.
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.
It occurs when light hitting the boundary between two media comes from a denser medium?
Total internal reflection occurs when light is traveling from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle. This causes the light to be reflected back into the denser medium rather than refracting out. It is commonly seen in situations like fiber optics.
What are the conditions of total internal reflection?
Total internal reflection occurs when a light ray traveling from a denser medium to a less dense medium strikes the interface at an angle greater than the critical angle. The critical angle is the angle at which the light ray is refracted along the interface. If the angle of incidence is greater than the critical angle, all of the light is reflected back into the denser medium.
What is Optical denser medium?
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
What two mediums have to be present for total internal reflection?
Any two media having different optical densities is necessary. The conditions for total internal reflection are: 1. Light must travel from the optically denser medium to the optically less dense one. 2. The angle of incidence is greater than the critical angle, which is the angle of incidence in the optically denser medium for which the angle of refraction is 90o.
Why is total internal reflection used?
Total internal reflection is used in fiber optics and prisms to efficiently guide and transmit light without loss. This occurs when a light ray traveling in a denser medium hits the boundary of a less dense medium at an angle greater than the critical angle, causing the light to reflect back into the denser medium rather than refracting out. This allows for the continuous transmission of light along the fiber or within the prism.
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.
