Is the angle of incidence greater than the angle of refraction?
In general, the angle of incidence is greater than the angle of refraction when light passes from a denser medium to a less dense medium, such as from water to air. This is described by Snell's Law, which states that the ratio of the sines of the angles is proportional to the ratio of the velocities of light in the two media. However, when light travels from a less dense medium to a denser one, the angle of incidence can be less than or equal to the angle of refraction.
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 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
Which direction will the ray bend?
The direction in which a ray bends depends on the medium it is passing through and the angle of incidence. If a ray travels from a less dense medium to a denser medium, it will bend towards the normal line. Conversely, if it moves from a denser medium to a less dense medium, it will bend away from the normal. This phenomenon is governed by Snell's Law.
What is the angle of incidence in an optically dense medium for which the angle of reflaction is 90 degrees?
Unfortunately, the word "reflaction" is one character different from reflection and refraction. It is not possible to determine which you meant.

When a light beam travels from a solid into a vacuum the angle of incidence is greater than the angle of refraction?
When a light beam travels from a solid into a vacuum, it moves from a denser medium to a less dense medium. According to Snell's Law, as light exits the denser medium (solid) into the less dense medium (vacuum), it speeds up, resulting in a larger angle of refraction compared to the angle of incidence. This phenomenon is due to the change in speed of light in different materials, leading to the observed relationship where the angle of incidence is greater than the angle of refraction.
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 will happen to the angle of refraction if the angle of incidence is made smaller for light passing from rarer to denser medium and how?
If the angle of incidence is made smaller for light passing from a rarer to a denser medium, the angle of refraction will also decrease. This is because of the law of refraction, which states that light bends towards the normal when moving from a rarer medium to a denser medium. Therefore, as the angle of incidence decreases, the angle of refraction will also decrease.
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.
What is total internal refraction?
Total internal reflection occurs when a light ray traveling from a dense medium to a less dense medium is reflected back into the denser medium, instead of being refracted. This phenomenon only occurs if the angle of incidence is greater than the critical angle, which depends on the refractive indices of the two mediums. Total internal reflection is the principle behind fiber optics and mirages.
When light waves refract and go into a slower medium the angle of incidence is what the angle of refraction?
When light waves refract from a faster medium to a slower medium, the angle of incidence is greater than the angle of refraction. This is known as Snell's Law, which describes the relationship between the angles of incidence and refraction when light passes through different mediums.
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 happens to waves when they enter a denser medium at a angle?
When waves enter a denser medium at an angle, they undergo refraction. This means the wave changes direction depending on the change in speed caused by the change in medium density. The angle of refraction depends on the angle of incidence and the refractive indices of the two media.
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...
If angle of incidence equals critical angle what is angle of refraction?
If the angle of incidence equals the critical angle, the angle of refraction would be 90 degrees. This occurs when light travels from a denser medium to a less dense medium and undergoes total internal reflection.
When light travels from less optically dense medium to more optically dense the angle of incidence is greater than the angle of refraction is it true?
Yes, that statement is true. When light travels from a less optically dense medium (like air) to a more optically dense medium (like water), the angle of incidence is greater than the angle of refraction. This phenomenon occurs due to the change in speed of light as it enters a denser medium, causing it to bend towards the normal line. This behavior is described by Snell's Law.
