this angle is called the critical angle of a substance. To work it out you must know the refractive index of that substance.

What are the terms related to refraction of light?

terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation


How does the angle of incidence compared with the angle of refraction for sound?

For refraction, the general relationship is given by Snell's Law.


Are angle of incidence and angle of refraction proportional?

No, the angle of incidence and angle of refraction are not directly proportional. They are related through Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums.


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.


If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?

The angle of refraction for a beam of light striking a diamond at an angle of 45 degrees will depend on the refractive index of the diamond material. The angle of refraction would be less than 45 degrees due to the bending of light as it enters the denser medium of the diamond.

For refraction to occur in a wave the wave must?

For refraction to occur in a wave, the wave must enter a new medium at an angle.


What is the definition of critical angle?

The definition of critical angle is the angle of incidence that refraction can still occur.


When will reflection and refraction occur simultaneously?

Reflection and refraction occur simultaneously when a light ray encounters a boundary between two different mediums at a specific angle known as the Brewster's angle. At this angle, the reflected and refracted rays are perpendicular to each other, allowing both phenomena to occur simultaneously.


What are the conditions necessary for refraction?

Refraction occurs when light passes from one medium to another of different optical density. The speed of light must change as it travels from one medium to another at an angle, causing it to bend. The angle of incidence must also be different from the angle of refraction for refraction to occur.


Does refraction occur only if rays are straight up and down?

No, refraction can occur whenever light rays pass through a medium with a different optical density. The amount of refraction depends on the angle at which the light rays enter the medium, not just if they are straight up and down.


If the angle of incidence increases and the indexes of refraction stay the same what happens to the angle of refraction?

The angle if refraction also increases.


What is the relationship between the angle of incidence and the angle of of refraction known as?

The COEFFICIENT of Refraction.


Does the index of refraction equal the angle of refraction?

Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index


Does doubling the angle of incidence cause the angle of refraction to double?

No, doubling the angle of incidence itself will not cause a doubling of the angle of refraction.


Will dispersion occur if a polychromatic ray of light enters a prism at an angle of incidence of 90 degree from air to denser medium?

Dispersion will occur, in the sense that the phase velocity of the different wavelengths will be different. What you may be asking is whether refraction (a change in the direction of the light) will occur. Refraction will only be visible if the light impacts at an oblique angle, not 90 degrees.


Why is the angle of refraction zero in newton's ring exp?

The angle of refraction is zero in Newton's ring experiment because the incident light is perpendicular to the plane of the glass plate, so refraction does not occur. This allows for constructive interference between the incident and reflected light waves, leading to the formation of interference rings.


Is the angle of refraction the same as the angle of reflection?

No.
