Is there a critical angle for angle for light going from glass to water?
Yes, there is a critical angle for light transitioning from glass to water. The critical angle occurs when light moves from a medium with a higher refractive index (glass) to one with a lower refractive index (water). If the angle of incidence exceeds this critical angle, total internal reflection occurs, meaning no light passes into the water. The critical angle can be calculated using Snell's Law.
When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
What is the critical angle for light traveling from water into air?
48.6 degrees
Why do bit rate decrease due to distance?
imagine that your connection in an tube of 10M with a 1degree angle You drop a glass of water in it. That take 10sec. imagine that your connection in an tube of 100M with 1degree angle, You drop a glass of water in it. How long the water take to reach the end ? The data is very comparable to water in drain.... Jean-François Cyr,
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.
Why critical angle for water is greater than the critical angle of glass?
Because of the difference in the density of the materials.
What is the critical angle of perspex and water?
The critical angle for perspex and water is approximately 41 degrees. This means that any light ray entering perspex from water at an angle greater than 41 degrees will be totally internally reflected within the perspex.
Is there a critical angle for angle for light going from glass to water?
Yes, there is a critical angle for light transitioning from glass to water. The critical angle occurs when light moves from a medium with a higher refractive index (glass) to one with a lower refractive index (water). If the angle of incidence exceeds this critical angle, total internal reflection occurs, meaning no light passes into the water. The critical angle can be calculated using Snell's Law.
What Critical angle of light passing from glass to water is minimum from?
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
Is there a critical angle for light traveling from glass to water?
Yes, there is a critical angle for light traveling from glass to water. This critical angle is the angle of incidence that results in light being refracted along the interface between the two mediums, rather than being transmitted into the other medium. The critical angle can be calculated using Snell's Law.
As a ray of light passes from air into glass the angle it makes with the surface normal will?
REFLECTION... (this is the right answer for: A ray of light strikes a flat surface of water. The angle that the reflected light ray makes with the normal is called the angle of? )if not incident ray.
What is the critical angle of water and how does it affect the phenomenon of total internal reflection?
The critical angle of water is the angle at which light traveling from water to air bends so much that it reflects back into the water instead of refracting out. This phenomenon, known as total internal reflection, occurs when the angle of incidence is greater than the critical angle. It is important in optical devices like fiber optics, where light is transmitted through materials by reflecting off their boundaries.
When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
What is the critical angle of glass?
When light in glass of index of refraction n hits the surface at angle A relative to the surface normal (perpendicular line to the surface) it generally exits into the air at larger angle B. These three variables are related by Snell's Law: n Sin(A) = (1)Sin(B) (air has index of refraction approx. = 1 ) The critical angle A for internal reflection occurs when the exit angle is 90 so the exit light skims the surface. Anything larger then critical A and the light gets reflected back into the glass. So in Snell's law let B = 90; nSin(A) =(1)Sin(90) = (1)(1) so Sin(A) = 1/n For glass n ~ 1.5 so Sin(A) ~ .67 This is the sine of the critical angle. Now figure out what angle has a sign of .67 and Whala you have it.

Is density of glass greater than that of water and why?
it depends on the type of glass you are talking about.
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.
