90o.
i think there will be no refraction there will be totally internal reflection

What is the critical angel?
The critical angel is the angle of incidence that yields an angel of refraction that is larger than the angels of incidence.
How do you compare the angle of incidence and the angle refraction?
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
Why is it necessary for the angle of refraction to be equal to the angle of incidence when the angle of incidence is zero?
when the angle of refraction is zero you still need an angle of incidence because it still reflects back.
When angle of incidence is equal to angle of refraction?
The second angle of incidence is equal to the angle of refractions.
What is the definition of critical angle?
The definition of critical angle is the angle of incidence that refraction can still occur.
Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
What is the critical angel?
The critical angel is the angle of incidence that yields an angel of refraction that is larger than the angels of incidence.
How do you compare the angle of incidence and the angle refraction?
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
What tajes place when the angle of incidence is smaller than the critical angle?
Refraction and partial internal reflection occurs
What is total internal refraction?
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
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.
Why is it necessary for the angle of refraction to be equal to the angle of incidence when the angle of incidence is zero?
when the angle of refraction is zero you still need an angle of incidence because it still reflects back.
The angle of reflection is equal to the .......?
The angle of incidence
Is the critical angle the same thing as the angle of incidence?
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.
When angle of incidence is equal to angle of refraction?
The second angle of incidence is equal to the angle of refractions.
