Which angle hits a mirror or glass block?
The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.
What is a piece of glass that has apolished flat sides at an angle?
A bevelled piece of glass.
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
What happens to the angle of incidence from air to glass?
The angle of incidence does not change. I think you want to know the relationship between the angle of incidence and the angle of transmission. In the case of from air to glas, the transmission angle is smaller than the angle of incidence due to a higher index of refraction of glass than that of air. Look up Snell's Law for better understanding.
How does the angle of incidence compare with the angle of refraction when light passes obliquely from air to glass?
same problem dude..
What is the angle of polarisation for a ordinary glass and water?
As per Brewster's law, the angle of polarisation or polarising angle is got by the expression tan ip = mu. So for water mu = 1.33 and its polarizing angle = 53 deg 3 min For glass mu would vary for different glass such as flint etc.
Who invented the first micros cope?
relation between critical angle and polarising angle?
Light traveling from air into glass has an angle of 45 degrees The angle of refraction in the glass is most likely?
27.7 degrees if the glass is crown glass.
Which angle hits a mirror or glass block?
The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.
If Light goes from flint glass into ethanol The angle of refraction in the ethanol is 27.6 What is the angle of incidence in the glass?
If light goes from flint glass into ethanol and the angle of refraction in the ethanol is 27.6, the angle of incidence in the glass is approximately 23.21. This calculation is based on refractive index of pure flint glass being 1.60 and refractive index of ethanol being 1.361.
Why does light bend when it goes through glass at an angle?
Change in speed of the light in glass. Fermat showed that time is invariant in light paths. This results in Light following the Law of Signs. sin(Air Angle)/speed in air = sin( Glass Angle)/speed in glass .
What is the critical angle of perspex and water?
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
What is a piece of glass that has apolished flat sides at an angle?
A bevelled piece of glass.
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
can calcite be used to make polarising microscopes?
yes
Is a martini glass an obtuse angle?
I found a picture of a martini glass, and doing my best to measure the angle from the picture on the monitor, it looks like the bottom angle is about 70°, and the angle between the top edge and horizontal is about 55°. So that one would not be an obtuse angle. See related link.
When light passes from air into glass which angle is always bigger?
The angle of incidence is always greater than the angle of refraction. The refractive index of glass is greater than that of air, so the speed of light in air is more than the speed of light in glass. Therefore it slows down and bends towards the normal.
