What Are Some Common Uses Of A Lever?
Common uses of a lever include opening a door, using a seesaw, lifting heavy objects with a crowbar, and using scissors to cut paper. Levers are simple machines that provide a mechanical advantage to make lifting or moving objects easier.
What are parallel and perpendicular polarisations?
Parallel polarisations are the divergence of the vibrations (Del . dV/dr) and Perpendicular polarisations are Curl of the vibrations (Del x dV/dr). The parallel polarisations is associated with the scalar wave and the perpendicular polarisations are associated with the vector wave.
Why are longitudinal wave not polarized?
Polarisation is specially related to limiting the vibrations in only one direction or a plane. This is possible in case of transverse waves. But in case of longitudinal only one direction of propagation ie to and fro is possible. So no chance of having the phenomenon of polarisation with longitudinal waves.
How does an unpolarised light incident on a polaroid get polarised describe briefly with diagram of polarisation of light by reflection through a transparent medium?
When unpolarised light passes through a polaroid, the polaroid selectively absorbs the light waves oscillating in one direction, allowing only light waves oscillating in the perpendicular direction to pass through. This results in the unpolarised light becoming polarised, with its electric field vibrating in a single plane. The diagram for polarisation of light by reflection through a transparent medium involves light waves hitting the medium's surface at an angle, with only the waves oscillating in a specific direction being transmitted while the others are absorbed or reflected.
Are there three things that can happen when light travels from one material to another?
Yes, when light travels from one material to another, it can be reflected (bounced off the surface), transmitted (passes through the material), or absorbed (taken in by the material).
What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
What do you mean by polarisation?
dont no that y im askind you durr
What is polarising?
When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.
What is molar polarisation?
Molar polarisation is the separation of positive and negative charges within a molecule or ion due to differences in electronegativity or other factors. This can result in a molecule having a partial positive and partial negative charge, making it polar.
What is the axial ratio antenna?
axial ratio is a prarameter for determining how good circular polarisation
Is there any difference between polarisation and polarization?
Only the spelling, they are two spellings for the same thing.
Is transverse nature of light waves is verified by refraction or not?
transverse nature of light is verified by polarisation.
What is cross polarization isolation?
Cross polarisation isolation or Cross Polarisation Discrinimation (XPD) is the difference in dB of received signal level (RSL) at the receiver when in turn, the transmitter has the same and different polarisation with the receiver. A antenna with this greater value is prefered. This information is useful in microwace design when in the same area we can use the same frequency with different polarisation . For example: TX1 : vertical polarisation ---> RX1 : Vertical pol. TX2 : horizontal pol. ---> RX2 : horizontal pol. They all operate in the same frequency. The signal from TX1 , TX2 will be separated corresponding to the value of XPD.

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.
What are some uses of an IRobot?
There are many uses of I robots. Some uses are for docking stations. Other uses are for products such as a robot vacuum, or a robot nurse in hospitals!
