How is the direction of aray of light changed when it travels from an optically denser to an optically rarer medium?
When light travels from an optically denser medium to an optically rarer medium, it bends away from the normal (angle of incidence is greater than angle of refraction) due to the decrease in the speed of light in the rarer medium. This phenomenon is known as refraction.
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.
A ray of light travelling from medium A to medium B bends away from the Norman Which medium is optically denser?
The ray of light bends away from the normal when traveling from a less optically dense medium (medium A) to a more optically dense medium (medium B). Therefore, medium B is optically denser in this scenario.
What are characteristics of refraction?
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
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.

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 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.
A ray of light travelling from medium A to medium B bends away from the Norman Which medium is optically denser?
The ray of light bends away from the normal when traveling from a less optically dense medium (medium A) to a more optically dense medium (medium B). Therefore, medium B is optically denser in this scenario.
When light rays enter a new medium at an angle what does the change in speed cause the ray to do?
The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.

When light travels from a less optically dense medium to an optically denser one it bends.which statemant describe the bending?
This bending of light is called refraction. It occurs because the speed of light changes as it moves from one medium to another, causing it to bend towards the normal line in the denser medium. The angle of refraction depends on the angle of incidence and the optical properties of the two media.
What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
When light passes through a denser medium what happens to the light?
a denser medium hav more no.of particles also > the no.of particles > the opposition provided for..... therefore both wavelength and speed of light changes but frequency remains the same.
How does light bend when it passes into a denser material?
The Ray of light bends toward the normal line. The reason is the light in the more dense region has slower speed. The relationship is given by the Law of Signs:sin(incident angel)/incident speed = sin(refracted angle)/dense speedSin(I)/vi = Sin(dense)/vd
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.
