The laws in Britain are: you are allowed to cut parts of the tree that are overhanging over the boundary line but you have to give back the parts you cut off or it's classed as stealing. Be careful though, if you cut the tree back into your neighbor's land then it is classed as trespassing and you could be fined. Also because of a government billing, local authorities now have the power to control what the owner of the tree can do if it really is restricting your light. They first issue a "remedial notice," which orders them to lower the height of the tree. If the owners do not listen, they could get a fine up to £1,000. Basically, you can't do anything about the blocking of light. Only if it actually crosses the property line. While an individual has some ability to control what happens over their property, there are limits. It would be pretty ugly if every airplane flight had to clear its flight path with every property owner it was going to cross over!
Any law to say what times garden fires can be lit in Cornwall
Is there law on neighbors overgrown trees blocking light from my lounge room window
Law garden
It is required by law in some places and if you block it off the check engine light will occasionally come on.
It is usually the US Supreme Court that can block a federal law. State Supreme Courts block states' laws. They can do this if the law is deemed unconstitutional or is in conflict with rights already protected in other laws.
There is no law in Physics or optics that is called law of light. There are laws that dictate specific properties or behaviour of light. Snell's law is one such law that tells us about refraction of light.
Yes. Don't start them.
When a ray of light enters a perspex block, it undergoes refraction, bending towards the normal due to the change in speed as it enters the denser medium. The angle of refraction is determined by Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two mediums.
Absolutely.
the block wall
To find the refractive index of a glass block for a particular wavelength of light, shine a beam of light of that wavelength through a material for which the refractive index n1 is known onto the glass block such that the angle between the beam and the block's surface θ1 is between zero and 90 degrees. Measure the angle between the part of the beam that enters the block and the block's surface θ2 and use Snell's law:n2 = n1 cos(θ1) / cos(θ2).Note: Typically Snell's law is expressed in terms of the angle between the beam and the direction normal to the interface and there for sines are used instead of cosines, but the use of cosines allowed the question to be answered without assuming knowledge of the concept "normal" to the interface.
As far as I know there is no law on the height of a single tree in one's own garden. There are by-laws about more than one tree where it can be argued it is a hedge,there are height restrictions on hedge heights. UK law.
