What happens when the angle of incidence is greater than the critical angle?
You get total internal reflection. That is, the incident beam bounces off the interface back into the medium.
Why does water have a greater critical angle than glass?
The critical angle is determined by the refractive indices of the two media involved. Water has a lower refractive index (approximately 1.33) compared to glass (which typically ranges from about 1.5 to 1.9). Since the critical angle is calculated using Snell's Law, a lower refractive index in water allows for a greater critical angle when transitioning from water to air, compared to the transition from glass to air. Thus, water's lower refractive index results in a larger critical angle.
When the angle of incidence is greater than the critical angle all light within the material is?
hte light is reflected
What happens to the light ray when the angle of incidence is greater than the angle of total reflection?
it is not the angle of total reflection, it is the critical angle. and when the angle of incidence is greater than the critical angle, total internal reflection takes place and as it is necessary for total internal reflection to take place that the ray must travel from denser to rarer medium so, when it occurs, the ray is reflected bach into the denser medium.
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 will happen to a light Ray incident on a glass-to-air boundary at greater than the critical angles?
If a light ray is incident on a glass-to-air boundary at an angle greater than the critical angle, total internal reflection will occur. This means that all of the light will be reflected back into the glass medium and none will be transmitted into the air.
What is is the term for the phenomena observed when the incident angle is made greater than the critical angle?
Total internal reflection occurs when the incident angle is greater than the critical angle, causing light to be reflected back inside the medium rather than refracting out of it. This phenomenon is commonly seen in prisms and optical fibers.
What happens when the angle of incidence is greater than the critical angle?
You get total internal reflection. That is, the incident beam bounces off the interface back into the medium.
What condition must be met before total internal refraction can occur?
Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle greater than the critical angle. The critical angle is specific to the two media involved and is determined by their refractive indices. Additionally, the light must be incident at an angle greater than this critical angle for total internal reflection to take place.
Why critical angle for water is greater than the critical angle of glass?
Because of the difference in the density of the materials.
What if your need is greater than mine write an incident in your life when this statement has come to your mind what do you mean by this statement?
"Your need is greater than mine"
Can a nulcear bomb have a core greater than its critical mass?
Yes.
When the refracted light is bent back into the incident material is called a?
When the refracted light is bent back into the incident material, it is called total internal reflection. This occurs when the angle of incidence is greater than the critical angle, causing all the light to be reflected back into the original medium rather than refracted. Total internal reflection is the principle behind optical fibers and mirages.
Is plutonium more powerful then uranium?
Plutonium is more dangerous: the specific activity is greater, the critical mass is smaller, the chemical toxicity is greater.
When and why the internal reflection occurs?
Total internal reflection occurs when a light hits its medium at an angle wider than a certain critical angle, depending upon what's normal to that medium. If the refractive index and the incident angle on the other side are measured lower or greater, respectively, the light is totally reflected.
What is critical in determining whether something is produced a public good?
It is critical in determining whether something is produced a public good if the benefit is greater than the cost.
What are the critical features of an inequality?
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
