Is this true or false light travels faster through water than it does through glass?
True
What makes a pole seem to bend when you put it in a glass of water?
The reason for the pole appearing bent when put inside a glass of water is refraction. When a ray of light travels through one medium to the other, it tends to bend or deviate from its original path. Thus a light ray in this case, travels from the air through water, and then again through air and reach the eyes. Thus, the light ray deviates from its original path causing this phenomenon.
What does a magnifying glass do to sun's heat and light?
when light goes into a magnifying glass, it simply reflects the air in the centre. E.G. if you points the magnifying glass at a leaf, a hole in the leaf will appears because all the light that was absorbed by the magnifying glass is reflected into the line of sight of the leaf.
Is it possible to have total internal reflection of light incident from air to glass?
If you mean that the light is in the glass, and the air is on the "outside", then yes. The other way it isn't possible; for total internal reflection, the material through which light travels must needs have a higher refractive index.
Why can you see through a solid glass window but not through an opaque object like a wall?
Electromagnetic radiation passes through materials it does not interact strongly with and which do not present many interfaces where there is a transition between materials of different density.
How light travels in glass and in wood?
through opticle fiber
How does light travels on a telephone call?
Light travels through what is fiber optic cabling. The cables are internally filled with long flexible tubes that are made of glass. The laser light travels through an individual glass tubing.
What material through which light travels through it?
glass
Is optical fiber ihollow or not?
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
How does light behaves when it travels from air through glass?
The answer depends on the medium which it then travels through.
When is light refracted?
light is refracted when it travels through air and then through glass
The colour of light which travels through glass with the minimum speed is?
Light does not change speed when it goes through glass.
What happens when a light ray travels through air into glass?
Light speed slows down in the glass.
When white light travels through a glass prism what colour is refracted through the smallest angle?
Red since red light travels the slowest
Which color travels through glass faster red or blue light?
Red light.
Why should the light ray be reflected rather than refractive in fiber optics?
Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection. Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics. In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.
Does light travel faster through air water vacuum or glass?
it travels faster through air.
