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.
When a ray of light passes from an optically denser to a racer medium it?
When a ray of light passes from an optically denser medium to a rarer medium, it bends away from the normal. This phenomenon is known as refraction. The speed of light changes as it moves from one medium to another, causing the change in direction.
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 happens to a ray of light that slows down when it hits a new medium at an angle?
When a ray of light slows down as it enters a new medium at an angle, it also changes direction. This change in speed and direction is called refraction. The amount by which the light bends depends on the difference in the speed of light between the two media.
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.
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.

What can speed up light?
Travelling through a medium that is optically less dense. Vacuum is best.

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 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.
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 effect on wavelength of light when it enter dense medium?
When light enters a denser medium than it was previously travelling in, the wavelength gets shorter because the speed of the light slows down: v=w/f where v is the velocity of a wave, w is the wave length, and f is the frequency. When light enters the new medium, f does not change but v decreases so w also decreases. Actually, the density of the medium is not accurate. The medium is not denser it just is "optically denser" which means it has a higher index of refraction. It has nothing to do with actual density, which is weight divided by volume.
What does less dense and denser medium mean?
A less dense medium refers to a substance that has fewer particles or less mass per unit volume compared to another medium. Conversely, a denser medium has more particles or more mass per unit volume. Light travels faster in a less dense medium and slower in a denser medium.
