What is used to indicate a Storm Warning observed forecast winds of 48 knots or greater?
The storm warning indicator for forecast winds of 48 knots or greater is a red burgee displayed above two red lights.
What flags are used to indicate a storm warning observed forecast winds of 48 knots or greater?
A storm warning for observed forecast winds of 48 knots or greater is indicated by displaying two red flags. When these flags are flown together, they signal that a storm is imminent and that mariners should take precautions. In addition to the flags, the warning may also be accompanied by specific advisories from meteorological services.
Why total internal reflection takes place?
It happens when light travels through a material that has a greater "optical density" (refraction index, really) than a bordering material, and when it touches the surface at an angle that is sufficiently flat.
What flag is used to indicate storm warning observed forecast winds of 48 knots or greater?
I think its the hotel flag, but either way its flapping
What score provides the most energy for atmospheric weather changes?
The score that provides the most energy for atmospheric weather changes is typically the "Convective Available Potential Energy" (CAPE). CAPE measures the amount of energy available for convection, indicating the potential for thunderstorms and severe weather. Higher CAPE values suggest greater instability in the atmosphere, which can lead to more intense weather phenomena. Thus, CAPE is a critical factor in forecasting severe weather events.
What will happen to a light ray incident on a glass-to-air boumdary at greater than the critical angle?
Anything greater than critical angle will cause the light to just be reflected.
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 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.
Why the observed frequency is greater than the frequency of the source?
The observed frequency can be greater than the frequency of the source due to the Doppler effect, where the relative motion between the source and observer causes a shift in the frequency of the wave. When the source is moving towards the observer, the observed frequency is higher, and when the source is moving away, the observed frequency is lower.
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.
Explain the phenomena of expansion observed up on freezing of water?
In solid form water molecules form hexagons with large empty spaces in the center, causing ice to be less dense than water. Therefore when water is frozen the ice created has a greater volume than the initial water due to conservation of mass.
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.
