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,
What describes the angle between water level and the incline of a water ski ramp?
An acute angle
Why is the water bond angle 104.5 less than the CH4 bond angle 109.5?
in water there are two bond pairs and two lone pairs where as in CH4 there are are four bond pairs nad no lone pair. in ch4 there is only bond pair to bond pair repulsion but in water there are three types of repulsions, lone to lone (greatest repulsion), lone to bond ( lesser repulsion ) and bond to bond ( the least repulsion) , therefore due to the presence of two lone pairs in water the bond pairs are repelled with greater force and they get compressed, reducing the ideal bond angle from 109.5 to 104.5 on the other hand, ch4 has only bond pairs and they dont repel each other that strongly so its angle is greater n its 109.5..
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.
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?
Decrease if the light is entering the glass at an angle greater than the critical angle, and increase if the light is entering the glass at an angle less than the critical angle. The angle the ray makes with the surface normal is known as the angle of refraction.
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.
What is the critical angle for light traveling from water into air?
48.6 degrees
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.
Which has a greater volume lead in water or glass in water?
This depends on the mass.
What is an example of total internal reflection at work?
An example of total internal reflection is when light strikes the boundary between water and air at an angle greater than the critical angle, causing all the light to be reflected back into the water instead of being transmitted. This is why you can see a reflection of the underwater scene when looking at a pond or swimming pool from a certain angle.
